In the Web Pages section, the top ten hits will come from the Direct Hit database if there are any matches there. Both the regular Lycos and Lycos Pro, their advanced search , use the Fast database as their search engine database. While that help file was still available in May 2001, the functions were not. Lycos originally automatically truncated search terms, and then switched in the summer of 1999 to no support for truncation. With the Fast database, there continues to be no truncation capabilities.
All search terms look for a match regardless of upper and lower case are searched.
The rest are most easily used via the form. Only this Host Pages have that specific domain. Exclude this Host Excludes pages from the specified domain. None in regular Lycos. In Lycos Pro, there are the field searches mentioned above and 25 language limits.
