Method Details

rewriteIndexExpressions

public static Map<String,List<String>> rewriteIndexExpressions(ProjectRoutingInfo originProject,
 List<ProjectRoutingInfo> linkedProjects,
 String[] originalIndices)

Rewrites index expressions for cross-project search requests. Handles qualified and unqualified expressions and match-all cases will also hand exclusions in the future.

Parameters:

originProject - the _origin project with its alias

linkedProjects - the list of linked and available projects to consider for a request

originalIndices - the array of index expressions to be rewritten to canonical CCS

Returns:

a map from original index expressions to lists of canonical index expressions

Throws:

IllegalArgumentException - if exclusions, date math or selectors are present in the index expressions

NoMatchingProjectException - if a qualified resource cannot be resolved because a project is missing
