Query

Single term query

The query specifies only one term for retrieving all documents which contain the term. e.g.,

intelligence

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.,

intelligence and dictionary

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

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.,

retail or utility

NOT query

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.,

utility not gas

Grouping

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

( retail or utility ) and intelligence not education

Phrase searching

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 the search engine, precision of phrase searching is not 100 %, so it causes wrong results occasionally. e.g.,

{corporate intelligence}

Substring matching

The are three types of substring matching searching.

Prefix matching

inter* (terms which begin with inter)

Inside matching

*text* (terms which contain text)

Suffix matching

*net (terms which terminated with net)

Notes

• In any queries, the search engine ignores case distinctions of alphabet characters. In other words, the search engine does case-insensitive pattern matching in any time.
• The search engine can handle a term which contains symbols like Product/Retail. Since this handling isn't complete, you can describe Product and Retail instead of Product/Retail, 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 {...}.
