When placed after a quoted phrase, ~ invokes proximity search.
#APACHE LUCENE FULL#
Placement determines whether a symbol is interpreted as an operator or just another character in a string.įor example, in Lucene full syntax, the tilde (~) is used for both fuzzy search and proximity search. The following syntax fundamentals apply to all queries that use the Lucene syntax. For details about the query request and parameters, including searchMode, see Search Documents (REST API). Whenever operators are on the query, you should generally set searchMode=all to ensure that all of the criteria is matched.įor more examples, see Lucene query syntax examples. While not specific to any query type, the searchMode parameter is relevant in this example. "search": "category:budget AND \"recently renovated\"^3", POST /indexes/hotels-sample-index/docs/search?api-version= Any documents containing the phrase "recently renovated" are ranked higher as a result of the term boost value (3). It looks for hotels where the category field contains the term "budget". This particular example shows in-field search and term boosting. The following example is a search request constructed using the full syntax.
In REST, query expressions are provided in the search parameter of a Search Documents (REST API) request. To use full Lucene syntax, you'll set the queryType to "full" and pass in a query expression patterned for wildcard, fuzzy search, or one of the other query forms supported by the full syntax. Much of the Lucene Query Parser syntax is implemented intact in Azure Cognitive Search, except for *range searches, which are constructed through $filter expressions. When creating queries in Azure Cognitive Search, you can opt for the full Lucene Query Parser syntax for specialized query forms: wildcard, fuzzy search, proximity search, regular expressions.
