Fulltext Searching

When a new knowledge document is stored or updated in powerKNOW the contents of the structure texts and supported attachments is analyzed and put into a separate fulltext index. This index is later on used to provide a powerfull and fast fulltext search mechanism.

Fulltext searching can be done by simply entering one or more fulltext search terms in the fulltext field and press the search button. Search terms are available for many types of searches.

Some examples:

xxx
Match whole word.
This will find the word xxx (caseblind).
Be aware that this is matching the whole word NOT the start of the word. Searching 'test' will match 'Test' but will NOT match 'testimony'.

xxx*
Match beginning of word.
This will find all words starting with xxx (caseblind).
Searching 'test' will match 'Test' and 'testimony' as well.

xxx AND yyy
Boolean operators are allowed for combining search terms.

(xxx OR yyy) AND zzz
Parentheses can be used to group multiple clauses.

"xxx yyy"~nn
Proximity search.
This is for finding words which are within a specified distance from each other.
E.g.: The term "yellow car"~10 will search for documents which contain 'yellow' and 'car' with both words within 10 words of each other.

For fulltext search we rely on the Lucene engine. For more details on the other possible types of searches / search terms (fuzzy search, ...) see: http://jakarta.apache.org/lucene/docs/queryparsersyntax.html

There are also some options available to modify / direct the fulltext search:

"restrict to keyword" checked
When doing a fulltext search only those documents will be listed which match the fulltext search criteria AND are associated with the currently selected keyword.
"search contents" checked
The fulltext search will be performed on the contents of the structure fields and the title of the knowledge documents.
"search attachments" checked
The fulltext search will not be done on the structure fields and the title of the knowledge documents but will be performed on the contents of the attachments instead.

xxx	Match whole word. This will find the word xxx (caseblind). Be aware that this is matching the whole word NOT the start of the word. Searching 'test' will match 'Test' but will NOT match 'testimony'.
xxx*	Match beginning of word. This will find all words starting with xxx (caseblind). Searching 'test' will match 'Test' and 'testimony' as well.
xxx AND yyy	Boolean operators are allowed for combining search terms.
(xxx OR yyy) AND zzz	Parentheses can be used to group multiple clauses.
"xxx yyy"~nn	Proximity search. This is for finding words which are within a specified distance from each other. E.g.: The term "yellow car"~10 will search for documents which contain 'yellow' and 'car' with both words within 10 words of each other.
