Search Results page
The Search Results page displays files for any search performed in the search entry field in the title area of any page. Each file is expandable to display all the lines that match the keyword. You can use right arrow key to pop up a 5-line context around the line. To view the file with the line located you can click on any match to open the editor. The page is designed to display multiple pages if the number of result files exceeds 40. To view more results you can use the previous and next page actions in the tool bar.
Starting search is very simple: just type or paste a keyword in the search entry field and hit enter. The result will be displayed in the same tab of your browser where you entered the keyword. The header of the result displays the total file number and the number range of the first page. Both literal and wild card search are supported. For example, "fo*ar" will hit all the files containing "foobar" while "fo??ar" will hit the same files. Please also note that the search ignores case.
If you start a search from a page where a folder is presented, or in another word, if bread crumb is presented, the place holder of the search entry field indicates the folder name on which your search will start. Currently the pages supporting this are navigator, git log, editor and search pages. For all other pages, the search will start from the project root. But once you are in the search result page, you can scope up and down for the same keyword.
Lets assume that you've just searched for "function" on a folder and you got 265 files but you want to see the results on a folder you are interested. You can now click on the location column where the interesting folder is presented. The result will be scoped down to that folder by the same keyword.
If your search result presents a sub folder but you want a broader scope, you can click on any segment in the bread crumb. The result will be scoped up to that folder by the same keyword.
Click Save Search in the tool bar to bookmark a link to this search for future use. Lets say you are searching "foo" on folder "bar". The default name of the saved search is "foo in bar" but you can rename it later to a more meaningful one. Note that this is a bookmark to the search, rather than a specific search result. Clicking on a link in the Searches list of the Favorites panel will perform a new search with the same search terms.
There are 4 actions in the tool bar for navigating matches. Expand all and Collapse all are convenient actions to view all matches or just view the file list. Up and Down allow you to just iterate all the files and matches top-down or bottom-up. While you are iterating, the current row is moving to indicate where you are. You can also jump over to a specific file or match by clicking on that row, which gives a quick switch-over to where you want to start the iteration. The current row is always cached as the browser's cookie based on the search URL. If you leave the page and come back or refresh the page, the current row is restored.
When search result page is loaded, the result pane is focused and the current row is highlighted where you can use the key board navigation. Note that key board navigation is available only when the result pane gets focus. If focus is not on the result pane, just click on any place in the result pane to get it back.
- To move the current row, use up and down arrow keys. You can also change the current row by clicking on the anywhere of any row.
- To expand or collapse the current row, use right and left arrow keys.
- To open a file or go to the matching line with that file, use Enter key.
- To open a file or go to the matching line with that file in a new tab, use Ctrl+Enter key.
There are two ways to view details on a match. When the current row is on a match, pressing right arrow key will pop up a context tip with 5 lines of code around the hit line. Note that if you use up and down arrow keys from now, the context tip changes contents when a match is iterated. Use left arrow key to cancel the context tip. If you want to view more details, press enter key or click on the link of the match. This will open the Orion editor with the line located at the matching place.
If the number of matching files exceeds the page size, which is 40 by default, the Next page and Previous page actions will appear in the tool bar. Although it is not recommended to change the search URL, but if you really want to view all the results in one page you can change the rows parameter to the total file number. In the example above you can change rows=265 so that the new search url will look like http://orion.eclipse.org/search/search.html#?sort=Path asc&rows=265&start=0&q=function+Location:/file/B2/bundles/*. Note that changing this to a large number should only be used in some rare cases, such as replacing more than 40 files at once. Please also note that this could slow down the search and introduce server timeout.
Sort by name or location
The matching files are sorted by the folder names by default. Click on the options on the tool bar and check Sort by Name to invoke the search again sorted by the file names.
Orion search is based on the file indexer on the server side. There may be some rare cases that your updated files are not synced up into indexer yet when you invoke the search. For example, if you search on foo and replace all the matches with bar in a file and then search on foo again right away. Depending on how many files on the server, the indexer may still hit the file but the file does not contain foo any more. In this case the file is greyed out in the result list but if you search gain later it will disappear from the list completely.
There are several limitations that will be addressed in the future releases.
- Case sensitive search is not supported.
- Phrase search separated by white space. Note that white space is escaped when passing the key word to the sever. For example, foo bar will be treated as foobar.
- When sorting by name, all the upper case file names are sorted in front of all lower cases.
Replace page allows you to replace all or part of the matches by a new string. You can select what files and which matches you want to replace with the replacing string. After all the selected files are replaced, a report page indicates the success or failure.
In the search result page, click on Replace on the tool bar to bring up the slide out. Type the replacing string and hit enter or click on Preview Changes to go to the replace page. Note you can also use ESC key or click on x to go back to the search page.
In the replace page, all the files and matches are displayed in a similar way as the result page does. In addition to that you can use check box to select the files and matches you want to replace. Note that if there are multiple matches in a single line, it will be split to multiple lines where each line represents one match. There are 3 levels of the check box.
- Overall: this allows you to toggle all the files and matches.
- File level: this allows you to toggle all the matches in a file.
- Match level: this allows you to toggle each match.
The key board navigation in replace page is similar to result page. But as the file and match names are not links to open the editor, enter key is not available. Also note that there is no context tip because you can view them in the compare view.
- To move the current row, use up and down arrow keys. You can also change the current row by clicking on the name column of any row.
- To expand or collapse the current row, use right and left arrow keys.
- To toggle the check box of the current row, use the space key.
- To select multiple rows, use shift+up/down keys.
When the replace page is loaded, the compare view is displayed by default at the bottom of the main pain. While you are iterating matches, the compare view highlights the difference for the current row. Note that you can click on Hide Compare on the tool bar to hide it for a smoother iteration and bring it back later by Show Compare.
Once you have selected all the matches that you want to replace, click on Commit on the tool bar. This will write all the replacement on the server.
After the changes are committed, the replace page displays a list of files indicating the success or failure of the replacement. It also reports on how many matches were replaced on each file. You can click on any file to see the new content in a new tab. If some body else has changed the same file while you are replacing, a failure is generated and you have to refresh the page to redo it. The report is not really a page by different URL. Refreshing the page will just restart the replacement.
Also note that if the changes happen on the working directory of a git repository, you can undo them in git status page.
Replacing page by page
As the search itself is based on pages, the replace is based on page as well. Click on Next pages or Previous pages to replace the same key word by the same replacing word.
Sample: refactor a function name
Lets say there is a function called foo that is used in 60 files. User A creates a new function called bar and wants to replace the function name in 5 files. In the mean while user B modified and saved one of the files. The steps below describes the complete work flow:
- User A searches on key word foo. In the first result page, there are 3 files that user A wants to replace.
- User A clicks on replace and types bar and hits enter.
- User A selects the 3 files and relative matches that will be replaced.
- User A compares and confirms the differences between the original and replaced lines.
- User A commits the new contents of the 3 files to the server.
- All the 3 files are written successfully indicated by the report.
- User A replaces the next page by selecting the remaining 2 files and relative matches.
- User B modifies one of the 2 files and saves it.
- User A commits the replacement.
- One of the 2 files is reported written failure because it was modified during the replacing.
- User A refreshes the page and replaces the failed file again.
- User A commits the replacement successfully.
- Optional: To undo the changes, user A checks out the changes in git status page.
