The query specifies two or more terms for retrieving all
documents which contain a first term but doesn't contain the
following terms. You can insert the not
operator between the terms to do NOT query. e.g.,
You can search for a phrase which consists of two or more terms
by surrounding them with double quotes like
"..." or with braces like {...}.
In Namazu, precision of phrase searching is not 100 %,
so it causes wrong results occasionally. e.g.,
You can use regular expressions for pattern matching. The
regular expressions must be surrounded by slashes like /.../. Namazu uses Ruby's regular
regular expressions engine. It offers generally Perl compatible flavor.
e.g.,
In any queries, Namazu ignores case distinctions of
alphabet characters. In other words, Namazu does
case-insensitive pattern matching in any time.
Japanese phrases are forced to be segmented into
morphemes automatically and are handled them as phrase searching. This processing
causes invalid segmentation occasionally.
Alphabet, numbers or a part of symbols (duplicated in
ASCII) characters which defined in JIS X 0208 (Japanese
Industrial Standards) are handled as ASCII characters.
Namazu can handle a term which contains symbols like
TCP/IP. Since this handling isn't complete,
you can describe TCP and IP instead of
TCP/IP, but it may cause noisy results.
Substring matching and field-specified searching takes
more time than other methods.
If you want to use and,
or or not simply as terms, you can
surround them respectively with double quotes like "..." or braces like {...}.
