Term completion. While typing into the simple search entry, a popup menu will appear and show completions for the current string. Values preceded by a clock icon come from the history, those preceded by a magnifier icon come from the index terms. This can be disabled in the preferences.
Picking up new terms from result or preview text. Double-clicking on a word in the result list or in a preview window will copy it to the simple search entry field.
Wildcards. Wildcards can be used inside search terms in all forms of searches. More about wildcards.
Automatic suffixes. Words like odt
or ods
can be automatically turned into query language
ext:xxx
clauses. This can be enabled in the
Search preferences panel in the GUI.
Disabling stem expansion. Entering a capitalized word in any search field will prevent
stem expansion (no search for
gardening
if you enter
Garden
instead of
garden
). This is the only case where
character case should make a difference for a Recoll
search. You can also disable stem expansion or change the
stemming language in the preferences.
Finding related documents. Selecting the Find similar documents entry in the result list paragraph right-click menu will select a set of "interesting" terms from the current result, and insert them into the simple search entry field. You can then possibly edit the list and start a search to find documents which may be apparented to the current result.
File names. File names are added as terms during indexing, and you can specify them as ordinary terms in normal search fields (Recoll used to index all directories in the file path as terms. This has been abandoned as it did not seem really useful). Alternatively, you can use the specific file name search which will only look for file names, and may be faster than the generic search especially when using wildcards.
