Example 1 with Operator

use of org.elasticsearch.index.query.Operator in project sonarqube by SonarSource.

the class RuleIndex method buildQuery.

/* Build main query (search based) */
private static QueryBuilder buildQuery(RuleQuery query) {
    // No contextual query case
    String queryText = query.getQueryText();
    if (StringUtils.isEmpty(queryText)) {
        return matchAllQuery();
    }
    // Build RuleBased contextual query
    BoolQueryBuilder qb = boolQuery();
    BoolQueryBuilder textQuery = boolQuery();
    JavaTokenizer.split(queryText).stream().map(token -> boolQuery().should(matchQuery(SEARCH_GRAMS_ANALYZER.subField(FIELD_RULE_NAME), StringUtils.left(token, DefaultIndexSettings.MAXIMUM_NGRAM_LENGTH)).boost(20F)).should(matchPhraseQuery(ENGLISH_HTML_ANALYZER.subField(FIELD_RULE_HTML_DESCRIPTION), token).boost(3F))).forEach(textQuery::must);
    qb.should(textQuery.boost(20F));
    // Match and partial Match queries
    // Search by key uses the "sortable" sub-field as it requires to be case-insensitive (lower-case filtering)
    qb.should(matchQuery(SORTABLE_ANALYZER.subField(FIELD_RULE_KEY), queryText).operator(Operator.AND).boost(30F));
    qb.should(matchQuery(SORTABLE_ANALYZER.subField(FIELD_RULE_RULE_KEY), queryText).operator(Operator.AND).boost(15F));
    qb.should(termQuery(FIELD_RULE_LANGUAGE, queryText, 3F));
    return qb;
