Feature Request: Exact match search #13

Closed DaemonF closed 12 years ago

DaemonF commented 12 years ago

There ought to be a way to force exact matches only rather than falling back to fuzzy search.

Use Case Example: Re-factoring sting constants that hold CSS class names out of code files. Project Type: Java / Google Web Toolkit (HTML / CSS / javascript)

I need to quickly search for all exact-match instances of a specific hard-coded CSS class name string in order to replace those string constants with a reference to a global static variable. The strings may contain non-alphanumeric characters such as hyphens and underscores which also need to be matched exactly.

Your extension does search the large project very quickly, for which I am grateful, but it matches items which don't match the search string. For example, searching "sidebar_widget_body" returns results for class names like "SidebarWidget" as well as even less exact matches. Fuzzy matching is great in many ways, but there should be a toggle to disable it!

Thanks, -DaemonF

Hi, It will do the fuzzy (similar) search if it can't find exact matches. You can disable similar match search in the plugin's preferences.

So "sidebar_widget_body" should get exact matches (please reopen the ticked if it doesn't). Words containing hyphens will be split at hyphens so exact matching won't work on those.

Regards, Andrejs

Wow, I completely missed that option in the preferences dialog, sorry! Still, Its a shame that hyphens aren't in the index's character set... They come up a lot in CSS and HTML. I assume that the index uses an intentional limited character set with something like a n-tree implementation, so it probably wouldn't be feasible to open it up to full UNICODE support without changing its data structure. If each node had a hash map from char to node it could do it, but at the cost of tons of memory...

Anyway, thanks for the quick response! -DaemonF

Hmm, even with the option for automatic fuzzy search turned off, I still get results like these: Screen Shot Even though fuzzy matching is off and the search term "newFriends" has only legal characters, only results 1-4 and 6 contain the phrase.

Hyphenated words are now supported in version 1.4

Wonderful! Thank you!
