public class PrefixSearchTupleSet<T extends Tuple<?>>
SearchTupleSet implementation supporting word prefix searches over indexed
Tuple data fields. This class uses a Trie
data structure
to find search results quickly; however, only prefix matches will be
identified as valid search matches. Multi-term search queries will result
in the union of the results for the individual query terms. That is, Tuples
that match any one of the terms will be included in the results.
For more advanced search capabilities, see
KeywordSearchTupleSet
or RegexSearchTupleSet

PrefixSearchTupleSet()
Creates a new KeywordSearchFocusSet that is not case sensitive. |

PrefixSearchTupleSet(boolean caseSensitive)
Creates a new KeywordSearchFocusSet with the indicated case sensitivity. |
Method Summary | |
---|---|
void |
clear()
Removes all search hits and clears out the index. |
java.lang.String |
getDelimiterString()
Returns the delimiter string used to divide data values and queries into separate words. |
java.lang.String |
getQuery()
Returns the current search query, if any. |
void |
index(Tuple<?> t,
java.lang.String field)
Indexes the given field of the provided Tuple instance. |
boolean |
isUnindexSupported()
Returns true, as unidexing is supported by this class. |
void |
search(java.lang.String query)
Searches the indexed Tuple fields for matching string prefixes, adding the Tuple instances for each search match to this TupleSet. |
void |
setDelimiterString(java.lang.String delim)
Sets the delimiter string used to divide data values and queries into separate words. |
void |
unindex(Tuple<?> t,
java.lang.String field)
Un-index an individual Tuple field, so that it can no longer be searched for. |
