public QueryConfiguration()

Method Details

setName

public QueryConfiguration setName(String name)

Should be a unique name of that query (e.g. "artNrSearch", "relaxedLevel1" etc) - it will be used in the result to assign the record matches to their matching query. It can also be used to reference to other queries as "fallback query" for some query builders.

Parameters:

name - unique config name

Returns:

self

setCondition

public QueryConfiguration setCondition(QueryConfiguration.QueryCondition condition)

Specify the search-term conditions to build the Elasticsearch query based on this configuration.

Parameters:

condition - set condition for that query config

Returns:

self

setStrategy

public QueryConfiguration setStrategy(String strategy)

Simple or canonical class name of the ESQueryFactory that is used to build that query. The suffix 'Factory' is optional.

Defaults to 'DefaultQueryFactory'. These ones are available:

• DefaultQueryFactory
• ConfigurableQueryFactory
• NgramQueryFactory
• PredictionQueryFactory

Parameters:

strategy - strategy name

Returns:

self

setWeightedFields

public QueryConfiguration setWeightedFields(Map<String,Float> weightedFields)

Defines the fields to be searched and their according weight.

The field name may contain a wildcard at the end to match all fields with a certain prefix. Keep in mind, that this will also match all subfields with different analyzers. For example 'title*' will search in 'title', 'title.standard', 'title.shingle', and 'title.ngram' with the same weight.

Parameters:

weightedFields - field names with weight > 0

Returns:

self

setSettings

public QueryConfiguration setSettings(Map<QueryBuildingSetting,String> settings)

Sets the QueryBuildingSettings for that query. Check the according QueryFactory to see which settings it supports.

Parameters:

settings - strategy specific settings

Returns:

self
