The "Include IFilters for HTML/XML based types" option is turned, on when this option is off, then finds flpro no keywords in the HTML files. In Windows XP 32 bit I must also enable this option, otherwise find the flpro also because no keywords.
I have tried various combinations in the settings of the program, also use the iFilters or not, I do not come on.
Maybe not a real HTML files that I have, but as mentioned, in Windows XP32 bit the presentation of search results always work correctly Wore.
