The advanced search dialog has fields that will allow a more refined search. It has a number of entry fields, each of which is configurable for the following modes:
All terms.
Any term.
None of the terms.
Phrase (exact terms in order within an adjustable window).
Proximity (terms in any order within an adjustable window).
Filename search with wildcards.
Additional entry fields can be created by clicking the Add clause button.
All relevant fields will be combined by an implicit AND or OR conjunction. All types of clauses except "phrase" and "near" can accept a mix of single words and phrases enclosed in double quotes. Stemming expansion will be performed for all terms not beginning with a capital letter, except for "phrase" clauses.
Advanced search will also let you search for documents of specific mime types (ie: only text/plain, or text/HTML or application/pdf etc...). The state of the file type selection can be saved as the default (the file type filter will not be activated at program start-up, but the lists will be in the restored state).
You can also restrict the search results to a sub-tree of the indexed area. If you need to do this often, you may think of setting up multiple indexes instead, as the performance will be much better.
Click on the Start Search button in the advanced search dialog, or type Enter in any text field to start the search. The button in the main window always performs a simple search.
Click on the Show query details link at the top of the result page to see the query expansion.
