The AGrep Search Engine is a text search DLL to be used with any kind of
Windows application. It has two possibilities:

- approximative search based on Baeza-Yates algorithm to find a pattern
which is only partly known (also known as search with erroneous
patterns). For example, you can search for "pattern" with 1 error (at
most) and it will match "pattern", "pittern" and "Pattern" while
stepping over "lantern" (2 errors).

- search modelled on the Unix utility named GREP. It is particularly
useful for complex searching with the help of its specific search
"language" to describe the pattern you look for. For example, you can
search for "^pattern" to look for "pattern" at the beginning of a line;
or for "[pl]a[nt]tern" to look for either "pattern" or "lantern". Look
into the Help file for an extensive description of the pattern language.

Both are particularly useful to improve greatly the search capability of
an existing tool such as a text editor, a data base search engine, etc.


The Windows help file gives detailed information about using it.
