Query

Single term query

This query specifies only one term for retrieving all of the documents which contain that term, for example:

copper

AND query

This query specifies two or more terms for retrieving all of the documents which contain both terms. Insert the and operator between the terms, e.g.

Copper and Register

You can omit the and operator. Terms which are separated by one ore more spaces are assumed to be an AND query.

OR query

This query specifies two or more terms for retrieving all documents which contain any one term. Insert the or operator between the terms, e.g.

Copper or Blitter

NOT query

This query specifies two or more terms for retrieving all of the documents which contain a first term but do not contain the following terms. Insert the not operator between the terms, for example:

Grouping

You can group queries by surrounding them by parentheses. The parentheses should be separated by one or more spaces. e.g.

( Copper or Blitter ) and Register not Memory

You can search for a phrase that consists of two or more terms by surrounding them with double quotation marks or braces such as "..." and {...}. In Namazu, the precision of phrase searching is not 100 %, so wrong results may occasionally occur. Example:

"Amiga DOS"

Substring matching

The are three types of searching by substring matching.

Prefix matching: blit* (terms which begin with blit)
Inside matching: *text* (terms which contain text)
Suffix matching: *value (terms which terminated with value)

Regular expressions

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 generally offers a Perl compatible flavor. e.g.,

/pro(gram|blem)s?/

Notes

In any queries, Namazu ignores case distinctions of alphabet characters; i.e. Namazu does case-insensitive pattern matching.
Namazu can handle a term which contains symbols like TCP/IP. Since this method of handling isn't complete, you can also describe the term as TCP and IP instead of TCP/IP, but it may cause noisy results.
Substring matching takes more time than other methods.
If you want to use and, or or not simply as terms, you can surround them with double quotes or braces like "..." or {...}.
