All known Subclasses: org.mmbase.storage.search.implementation.BasicStringSearchConstraint,
| StringSearchConstraint | | public interface StringSearchConstraint extends FieldConstraint(Code) | | A constraint specifically for advanced types of text searches.
In addition to searchterms, a search type and a
match type can be specified:
The search type specifies how the search is performed:
Must be one of:
The match type specifies how individual words in the
search terms are matched with words in the searched text.
The searchterms may containt the following wildchard characters as well:
- % for any string
- _ for a single character
Depending on searchtype and searchmode, the following parameters
can be set:
-
StringSearchConstraint.PARAM_FUZZINESS PARAM_FUZZINESS -
Float, specifies maximum allowed number of
typo's per word, expressed as fraction of word length.
(E.g. 0,2 means: maximum 2 typo's for 10 letter words.).
This parameter is only relevant when used with match type
MATCH_TYPE_FUZZY.
It can only be set for this match type, and is cleared when
the match type is set to another value.
-
StringSearchConstraint.PARAM_PROXIMITY_LIMIT PARAM_PROXIMITY_LIMIT -
Integer, specifies maximum distance between
searched words.
This parameter is only relevant when used with search type
SEARCH_TYPE_PROXIMITY_ORIENTED.
It can only be set for this search type, and is cleared when
the search type is set to another value.
