Search method | Search result in TAYCA site

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/

For all search methods, upper- and lower-case characters are not distinguished.
Japanese compound words are divided into units of morphemes for phrase searches. They may be divided improperly.
Partial alphanumeric characters and symbols (which overlap with ASCII) based on JIS X 0208 (i.e. full-size characters) are treated as ASCII (i.e. half-size characters).
Words containing symbols can be searched. Example: TCP/IP. However, symbols cannot be treated completely. Therefore, these symbols are more completely treated by dividing them, as in TCP and IP, and making an AND search (Excessive files may be searched instead).
It is slightly time-consuming to make intermediate, suffix, regular expression, and field-specified searches.
Enclose them using double quotation marks ("...") or braces ({...}) when you want to search “and”, “or”, and “not” as words.
