The search field, normally at the Lister's top right, now supports multiple methods:
Windows Search – As in Opus 12.
Everything search – If Voidtools Everything (see separate section) is installed, you can use it for an indexed search on the current folder.
Global Everything search – Similar to Everything search, but searches all indexed folders on the entire machine.
Opus search – You can now use Opus's own Find Files functionality from the Search Field, without opening the larger Find panel:
If a plain string or a wildcard is entered, it will be treated as a wildcard name match.
If a string beginning with = is entered, it'll be processed by the Evaluator and can perform more complex queries (e.g. =size>100kb).
Click the magnifying glass icon on the left to open a menu where you can change search engine.
The menu for changing search engines also lets you configure various options for each one (e.g. case sensitive, partial match, content searching). Each search engine has slightly different options.
The last chosen search engine is remembered automatically.
You set the search field's arguments to (e.g.) everything to make it always switch to that mode in new windows.
Search field has a history menu on the right, with a Clear History option at the bottom of the menu.
Suggestions based on search history will appear as you type into the search field. (Add noautocomplete to the field's arguments if you don't like them appearing.)
Commands:
Find and similar commands let a search engine be specified and support options as part of the command line.
Example, Windows search: QUERYENGINE="windows,nqs,noautowildcard,nohistory"
Example, Everything: QUERYENGINE="everything,case,wholeword,regex,diacritics"
