createAnalyzerForIndexing

public static final com.atlassian.jira.issue.index.JiraAnalyzer.PerFieldIndexingAnalyzer createAnalyzerForIndexing()

DELTA-537: Helper method for creating consistently configured analyzers for indexing. Created to avoid direct usage of JiraAnalyzer#ANALYZER_FOR_INDEXING in tests

createAnalyzerForSearching

protected static final org.apache.lucene.analysis.Analyzer createAnalyzerForSearching()

DELTA-537: Helper method for creating consistently configured analyzers for search. Created to avoid direct usage of JiraAnalyzer#ANALYZER_FOR_SEARCHING in unit tests, which may cause issues when reused in multiple tests with different language settings. Analyzers reuse TokenStreamComponents(which on turn have languge specific configuration) so using static final analyzer with perticular language set may lead to unpredictable results in other tests relying on the same analyzer.
