i am making a dictionary/find next viewer

[fugot]

i am change the search viewer so it can search text files for a certain word or phrase. the search viewer will search .m3u playlists. currently if you rename a the ending of a text file from .text to .m3u you can use the search viewer. if you do that it will search the file just fign. i have tested this on the rockbox dictionary format which is one line per word, starting with the word, then a tab and then the description . so all i want to do is cange the search viewer so it will also search text files. how would i do this?
