RegexpQuery ( field, value )
Matches documents that have fields matching a regular expression.

Method Summary
| Returns | Name | Description |
|---|---|---|
String | _type() | The type of ejs object. For internal use only. |
Object | boost(boost) | Sets the boost value of the Query. |
Object | field(f) | The field to run the query against. |
Object | flags(f) | The regex flags to use. Valid flags are:
INTERSECTION - Support for intersection notation
COMPLEMENT - Support for complement notation
EMPTY - Support for the empty language symbol: #
ANYSTRING - Support for the any string symbol: @
INTERVAL - Support for numerical interval notation: |
Object | flagsValue(v) | The regex flags to use as a numeric value. Advanced use only,
it is probably better to stick with the flags option. |
Object | rewrite(m) | Sets rewrite method. Valid values are: constant_score_auto - tries to pick the best constant-score rewrite method based on term and document counts from the query scoring_boolean - translates each term into boolean should and keeps the scores as computed by the query constant_score_boolean - same as scoring_boolean, expect no scores are computed. constant_score_filter - first creates a private Filter, by visiting each term in sequence and marking all docs for that term top_terms_boost_N - first translates each term into boolean should and scores are only computed as the boost using the top N scoring terms. Replace N with an integer value. top_terms_N - first translates each term into boolean should and keeps the scores as computed by the query. Only the top N scoring terms are used. Replace N with an integer value. Default is constant_score_auto. This is an advanced option, use with care. |
String | toJSON() | Retrieves the internal query object. This is typically used by
internal API functions so use with caution. |
Object | value(p) | The regexp value. |
Method Detail
boost
Object boost ( boost )
Sets the boost value of the Query.
|
field
Object field ( f )
The field to run the query against.
|
flags
Object flags ( f )
The regex flags to use. Valid flags are:
INTERSECTION - Support for intersection notation
COMPLEMENT - Support for complement notation
EMPTY - Support for the empty language symbol: #
ANYSTRING - Support for the any string symbol: @
INTERVAL - Support for numerical interval notation:
|
flagsValue
Object flagsValue ( v )
The regex flags to use as a numeric value. Advanced use only,
it is probably better to stick with the flags option.
|
rewrite
Object rewrite ( m )
Sets rewrite method. Valid values are:
constant_score_auto - tries to pick the best constant-score rewrite
method based on term and document counts from the query
scoring_boolean - translates each term into boolean should and
keeps the scores as computed by the query
constant_score_boolean - same as scoring_boolean, expect no scores
are computed.
constant_score_filter - first creates a private Filter, by visiting
each term in sequence and marking all docs for that term
top_terms_boost_N - first translates each term into boolean should
and scores are only computed as the boost using the top N
scoring terms. Replace N with an integer value.
top_terms_N - first translates each term into boolean should
and keeps the scores as computed by the query. Only the top N
scoring terms are used. Replace N with an integer value.
Default is constant_score_auto.
This is an advanced option, use with care.

toJSON
String toJSON ( )

internal API functions so use with caution.
