The recoll program provides the user interface for searching. It is based
on the QT library.
+ recoll has two search modes:
+
+ * Simple search (the default, on the main screen) has a single entry
+ field where you can enter multiple words.
+
+ * Advanced search (a panel accessed through the Tools menu or the
+ toolbox bar icon) shas multiple entry fields, which you may use to
+ build a logical condition, with additional filtering on file type and
+ location in the file system.
+
+ In most cases, you can enter the terms as you think them, even if they
+ contain embedded punctuation or other non-textual characters. For exemple,
+ Recoll can handle things like e-mail addresses, or arbitrary cut and paste
+ from another text window, punctation and all.
+
+ The main case where you should enter text differently from how it is
+ printed is for east-oriental languages written with Chinese characters.
+ Words composed of single or multiple characters should be entered
+ separated by white space in this case (they would typically be printed
+ without white space).

* MP3: Recoll will use the id3info command from the id3lib package to
extract tag information. Without it, only the file names will be
indexed.

Text, HTML, mail folders Openoffice and Scribus files are processed
internally. Lyx is used to index Lyx files. Many filters need sed and awk.
