Overview
This class presents a DSL for constructing queries using the Sunspot.search method. Methods of this class are available inside the search block. Much of the DSL’s functionality is implemented by this class’s superclasses, Sunspot::DSL::FieldQuery and Sunspot::DSL::Scope
See Sunspot.search for usage examples

Instance Method Details
#fulltext(keywords, options = {}, &block) ⇒ Object Also known as: keywords
Specify a phrase that should be searched as fulltext. Only text
fields are searched - see DSL::Fields.text
Keyword search is executed using Solr’s dismax handler, which strikes a good balance between powerful and foolproof. In particular, well-matched quotation marks can be used to group phrases, and the + and - modifiers work as expected. All other special Solr boolean syntax is escaped, and mismatched quotes are ignored entirely.
This method can optionally take a block, which is evaluated by the Fulltext DSL class, and exposes several powerful dismax features.
Parameters
- keywords<String>
-
phrase to perform fulltext search on
Options
- :fields<Array>
-
List of fields that should be searched for keywords. Defaults to all fields configured for the types under search.
- :highlight<Boolean,Array>
-
If true, perform keyword highlighting on all searched fields. If an array of field names, perform highlighting on the specified fields. Note that for highlighting to work, the desired fields have to be set up with :stored => true. This can also be called from within the fulltext block.
- :minimum_match<Integer>
-
The minimum number of search terms that a result must match. By default, all search terms must match; if the number of search terms is less than this number, the default behavior applies.
- :tie<Float>
-
A tiebreaker coefficient for scores derived from subqueries that are lower-scoring than the maximum score subquery. Typically a near-zero value is useful. See wiki.apache.org/solr/DisMaxRequestHandler#tie_.28Tie_breaker.29 for more information.
- :query_phrase_slop<Integer>
-
The number of words that can appear between the words in a user-entered phrase (i.e., keywords in quotes) and still match. For instance, in a search for “"great pizza"” with a phrase slop of 1, “great pizza” and “great big pizza” will match, but “great monster of a pizza” will not. Default behavior is a query phrase slop of zero.
