THE FURUKAWA ELECTRIC site search

How to search

Input keywords or query in the [keywords/query] box, and hit [SEARCH] button. Then search results are displayed.
You can select the method of display in the pull-down menu below [keywords/query] box.

Display	Selecting the number of search results in one screen.
Description	Selecting the format of displaying the search results. In 'Normal' format, the summery of documents is shown partially. In 'Short' format, the summery is not shown.
sort:	Selecting the sort key of listing the search results. In default setting, the search results are listed by 'score'. The 'score' is calculated from the frequency of the keywords appearing in the document, especially in the 'important' part of document, just like title or caption.

Query

Single term query	The query specifies only one term for retrieving all documents which contain the term. e.g. `FURUKAWA`
AND query	The query specifies two or more terms for retrieving all documents which contain both terms. You can insert the `and` operator between the terms e.g., `FURUKAWA ELECTRIC` You can ommit the `and` operator. Terms which is separated by one ore more spaces is assumed to be AND query e.g., `FURUKAWA and ELECTRIC`
OR query	The query specifies two or more terms for retrieving all documents which contain either term. You can insert the `or` operator between the terms. e.g., `ELECTRIC or ELECTRONICS`
NOT query	The query specifies two or more terms for retrieving all documents which contain a first term but does't contain the following terms. You can insert the `not` operator between the terms to do NOT query. e.g., `ELECTRIC not MECHANIC` >
Grouping	You can group queries by surrounding them by parentheses. The parentheses should be separated by one or more spaces. e.g., `FURUKAWA and ( ELECTRIC or ELECTRONICS ) not MECHANIC`
Substring matching	There are three types of substring matching searching. Prefix matching `ELEC` (terms which begin with `ELEC`) Inside matching `OPT` (terms which contain `OPT`) Suffix matching `FIBER` (terms which terminated with `FIBER`)

Notes

In any queries, case distinctions of alphabet characters is ignored. In other words, the site search does case-insensitive pattern matching in any time.
The site search 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 {...}.
