Set AdvancedSearch
to True
to use an advanced weighting algorithm that improves conceptual querying.
Enabling AdvancedSearch
allows you to search for an exact word or phrase match. When you query for a word or phrase that is enclosed in quotation marks, HPE IDOL Server matches it in its exact unstemmed form (query text that is not enclosed in quotation marks is still matched conceptually).
AdvancedSearch
is not affected by enabling or disabling stemming.
Enabling AdvancedSearch
has no notable effect on the HPE IDOL Server index size.
Enabling AdvancedSearch
does not prevent HPE IDOL Server from discarding stop words at index and at query time.
If you enable AdvancedSearch
, HPE recommends that you set ProperNames to 7
in the appropriate language type sections of the configuration file.
If you enable AdvancedSearch
, you can still run a conceptual phrase search that uses stemming by using DNEAR1
.
Word Match Example
action=Query&Text="lovely"
HPE IDOL Server does not apply stemming.
When it matches the query, HPE IDOL Server returns only documents that contain a word that exactly matches the query word. The query "lovely"
can return only documents that contain the word lovely.
Phrase Match Example
action=Query&Text="fresh and lovely"
HPE IDOL Server removes any stop words that the query contains (the example query above contains the stop word and) but does not apply stemming:
action=Query&Text="fresh lovely"
When it matches the query, HPE IDOL Server returns only documents that contain a phrase that matches the phrase in the query string. The query fresh and lovely can return only documents that contain a phrase that matches the phrase fresh lovely (for example, fresh lovely, fresh and lovely, fresh or lovely, and so on).
