Additional search interface options

You can configure other features for the search interface by specifying other match-related attributes to the SEARCH_INTERFACE element.

The following table lists the attributes (other than the CROSS_FIELD_BOUNDARY attribute) that you can specify with the SEARCH_INTERFACE element.

Attribute	Purpose
`DEFAULT_RELRANK_STRATEGY`	For record search, assigns a default relevance scoring function to a search interface.
`CROSS_FIELD_RELEVANCE_RANK`	Specifies the relevance rank score for cross-field matches. The value should be an unsigned 32-bit integer. The default value for `CROSS_FIELD_RELEVANCE_RANK` is 0.
`STRICT_PHRASE_MATCH`	Specifies that the Dgraph process should interpret a query strictly when comparing white space in the query with punctuation in the source text. If set to FALSE, partial word tokens connected in the source text by punctuation can be matched to a phrase query where the partial tokens are separated by spaces instead of matching punctuation. The default value of this attribute is TRUE.
