Search method

Single word search
This is the most basic search method via which you specify only one word to be examined.
Example: titanium
AND search
This searches a document contaning both a certain word and a certain word. This search is effectivefor narrowing down a search result. It also enables three or more words to be specified. Insert and between words.
Example: titanium and cosmetics
and” can be omitted. When words are delimited using a blank, a document containng these all words is AND-searched.
OR search
This searches a document containing either a certain word or a certain word. This search also enables three or more words to be specified. Insert “or” between words.
Example: titanium or cosmetics
NOT search
This searches a document containing a certain word and not containing a certain word. This search also enables three or more words to be specified. Insert “not” between words. Example:
Example: paints not cosmetics
Grouping
This search enables AND, OR, and NOT searches to be grouped using parentheses. Put blanks on both ends of parentheses.
Example: ( titanium or surfactants ) and cosmetics not paints
Phrase search
This searches a compound word consisting of two or more words. Enclose the words using double quotation marks ("...") or braces ({...}). The phrase search of Namazu may sometimes fail because it is not 100% precise.
Example: {titanium dioxide}
Partial search
Prefix, intermediate, and suffix searches are available as partial searches.
Prefix search: inter* ( Searches a document containing words beginning with inter. )
Intermediate search?*text* ( Searches a document containing words in which a text is involved. )
Suffix search: *net ( Searches a document containing words ending in net. )
Regular expression search
Specify the keywords to be searched for by regular expressions. For regular expressions, enclose words using slash symbols (/.../). A Ruby code is used for the engine of regular expression. The format of the regular expression is almost the same as for Perl.
Example: /tayca/
