public interface IPTSModifiableQuery
Base interface for all search queries that can be modified with
extra options such as spell correction, thesaurus, etc. Full-text and
metadata queries typically could be modified, but collection or
security queries usually are not. Queries that have child queries
(e.g. IPTSBooleanQuery
) are usually modifiable as well,
and the selected modification options apply to any child queries
that are also modifiable.
Method Summary | |
---|---|
void |
useBestBets(java.lang.String trigger)
Return best bet targets for the provided trigger string as the first results for this query. |
void |
useSpellCorrection()
Spell-correct this query. |
void |
useThesaurus()
Expand tokens in this query using the thesaurus. |
Method Detail |
---|
void useSpellCorrection()
IPTSBooleanQuery
, all child queries are spell-corrected as
well.
Note that there is no way to turn off spell-correction on a single child
IPTSQuery
. Be sure that none of this query's subqueries contain
constraints that should not be spell-corrected, such as ID or security constraints.
void useThesaurus()
IPTSBooleanQuery
, the thesaurus is applied
to all child queries as well.
Note that there is no way to turn off thesaurus usage on a single child
IPTSQuery
. Be sure that none of this query's subqueries contain
constraints that should not use the thesaurus, such as ID or security constraints.
void useBestBets(java.lang.String trigger)
Note that the best bet target results do not need to match the query
to be returned. This means you must be careful to call useBestBets
on the correct IPTSQuery
in a query tree. For example, suppose
your complete tree is ((TextQuery for dog
) AND (in folder 27)).
In this case, "TextQuery for dog
", "folder 27",
and the top-level BooleanQuery (AND
) are all separate
IPTSQuery
objects. If you call useBestBets
on
the TextQuery
, the folder restriction will be applied to the
best bet targets as well as the other results, so you will only get targets
in folder 27. If you call useBestBets
on the top-level
BooleanQuery
instead, you will see best bet targets regardless
of the folder they are located in.
trigger
- the best bet trigger string for this query, or null
to turn off use of best bets for this query.
