1)   Find In Context 2.00
Automatically shows relevant text fragments found with NEAR keyword search through local/LAN files; then you can browse through bigger fragments to see the context. Supports any file formats, HTML-aware. Very fast, flexible and effective NEAR search.

 2)   Wanyword 4.00
Text search with Boolean and NEAR or proximity operators. ANSI/OEM search and conversion on the fly which is not unimportant since there is a lot of old DOS text around and umlauts and accents may give problems here. Sets of found files can be saved.
