Class SolrSearchExpressionProcessor

  • All Implemented Interfaces:
    com.ibm.commerce.foundation.internal.server.services.dataaccess.datamediator.DataMediator

    public class SolrSearchExpressionProcessor
extends AbstractSearchExpression
implements com.ibm.commerce.foundation.internal.server.services.dataaccess.datamediator.DataMediator

    An implementation of DataMediator to process Solr expression. This search expression processor will compose the final Solr expression and set up all requirement bootstrap setting for communicating to the Solr search server. The result set will then be mediated into an EntityContainer object to be returned to the caller.

    This expression processor performs the following high level steps in this given order:

    1. Injects a debug parameter option into SolrQuery object by calling SolrSearchDebugQueryPreprocessor;
    2. Includes a relevancy score and additional tracing information into SolrQuery object by calling SolrSearchPreviewQueryPreprocessor;
    3. Enables spell correction and includes its associated parameter options into SolrQuery object by calling SolrSearchSpellCorrectionQueryPreprocessor;
    4. Enables highlighter and includes its associated parameter options into SolrQuery object by calling SolrSearchHighlighterQueryPreprocessor;
    5. Injects pagination parameter options into SolrQuery object by calling SolrSearchPaginationQueryPreprocessor;
    6. Injects sorting parameter option into SolrQuery object by calling SolrSearchSortingQueryPreprocessor;
    7. Injects result grouping parameter option into SolrQuery object by calling SolrSearchResultGroupingQueryPreprocessor;
    8. Generates a list of index field to be included in the search result set by calling SolrSearchResultFieldQueryPreprocessor;
    9. Composes a list of facet field, along with the proper settings, to be included in the search result set by calling SolrSearchFacetQueryPreprocessor;
    10. Injects the main search query string into SolrQuery object by calling SolrSearchMainQueryPreprocessor;
    11. Launches a list of search query pre-processors defined in the given search profile so as to allow modifying the SolrQuery object right before sending to Solr server for processing;
    12. Attempts to connect to Solr server, with retry logics upon connection failures, to process SolrQuery object;
    13. Launches a list of search query post-processors defined in the given search profile so as to allow modifying the physical data object, SolrEntityContainerImpl, right after the QueryResponse is returned from the Solr server.
