List of boost() Examples

Examples of boost()

com.sematext.searchschemer.index.FieldAttributes.boost()
Returns field boost. @return boost
org.apache.lucene.document.Field.boost()
{@inheritDoc}
The default value is 1.0f (no boost). @see #setBoost(float)
org.apache.lucene.index.IndexableField.boost()
Returns the field's index-time boost.
Only fields can have an index-time boost, if you want to simulate a "document boost", then you must pre-multiply it across all the relevant fields yourself.
The boost is used to compute the norm factor for the field. By default, in the {@link Similarity#computeNorm(FieldInvertState)} method, the boost value is multiplied by the length normalization factor and then rounded by {@link DefaultSimilarity#encodeNormValue(float)} before it is stored in theindex. One should attempt to ensure that this product does not overflow the range of that encoding.
It is illegal to return a boost other than 1.0f for a field that is not indexed ( {@link IndexableFieldType#indexed()} is false) or omits normalization values( {@link IndexableFieldType#omitNorms()} returns true). @see Similarity#computeNorm(FieldInvertState) @see DefaultSimilarity#encodeNormValue(float)
org.apache.lucene.queryParser.MultiFieldQueryParserSettings.boost()
org.apache.lucene.queryParser.QueryParserSettings.boost()
org.apache.lucene.queryparser.classic.QueryParserSettings.boost()
org.elasticsearch.index.mapper.FieldMapper.boost()
org.elasticsearch.index.mapper.core.StringFieldMapper.ValueAndBoost.boost()
