If you have trouble with searching, you can check the following tips.

Check a spelling of your keyword
Namazu can't find anything with wrong spelling.
Add keywords
If you gained no results or too few results, you can add one or more related keywords with or operator. It makes your search more hittable. e.g.,
tex or ptex or latex or latex2e
If you gaind too many results, you can add one or more related keywords with and operator. It makes your search more limited. e.g.,
latex and dvi2ps and eps
Try substring matching
If you gained no results or too few results, you can try substring matching. You can specify tex* to search for terms which begin with tex (e.g., tex, texi2html, texindex, text).
You can specify *tex to search for terms which terminated with tex (e.g., bibtex, jlatex, latex, platex, ptex, vertex).
You can specify *tex* to search for terms which contain tex (many).
You tried phrase searching but it hit documents which didn't contain your phrase.
It's a defect of Namazu. Precision of phrase searching is not 100 %, so it cause wrong results occasionally.
You want to use and, or or not as ordinary keywords
You can surround them respectively with double quotes like "..." or braces like {...}.
