Overrides:

search in class CmsSearchIndex

Parameters:

cms - the current user's Cms object

the List of results found or an empty list

search

public CmsSolrResultList search(CmsObject cms,

                         throws CmsSearchException

Default search method.

Parameters:

cms - the current CMS object

query - the query

Returns:

the results

Throws:

CmsSearchException - if something goes wrong

See Also:

• search(CmsObject, String)

search

public CmsSolrResultList search(CmsObject cms,
 CmsSolrQuery query,
 boolean ignoreMaxRows)
                         throws CmsSearchException

Performs a search.

Returns a list of 'OpenCms resource documents' (CmsSearchResource) encapsulated within the class CmsSolrResultList. This list can be accessed exactly like an List which entries are CmsSearchResource that extend CmsResource and holds the Solr implementation of I_CmsSearchDocument as member. This enables you to deal with the resulting list as you do with well known List and work on it's entries like you do on CmsResource.

What will be done with the Solr search result?

• Although it can happen, that there are less results returned than rows were requested (imagine an index containing less documents than requested rows) we try to guarantee the requested amount of search results and to provide a working pagination with security check.
• To be sure we get enough documents left even the permission check reduces the amount of found documents, the rows are multiplied by '5' and the current page additionally the offset is added. The count of documents we don't have enough permissions for grows with increasing page number, that's why we also multiply the rows by the current page count.
• Also make sure we perform the permission check for all found documents, so start with the first found doc.

NOTE: If latter pages than the current one are containing protected documents the total hit count will be incorrect, because the permission check ends if we have enough results found for the page to display. With other words latter pages than the current can contain documents that will first be checked if those pages are requested to be displayed, what causes a incorrect hit count.

Parameters:

cms - the current OpenCms context

query - the OpenCms Solr query

ignoreMaxRows - true to return all all requested rows, false to use max rows

Returns:

the list of found documents

Throws:

CmsSearchException - if something goes wrong

Parameters:

cms - the current OpenCms context

query - the OpenCms Solr query

filter - the resource filter to use for post-processing.

Returns:

                         throws CmsSearchException

Performs the actual search.

Parameters:

cms - the current OpenCms context

query - the OpenCms Solr query

ignoreMaxRows - true to return all all requested rows, false to use max rows

response - the servlet response to write the query result to, may also be null

ignoreSearchExclude - if set to false, only contents with search_exclude unset or "false" will be found - typical for the the non-gallery case

search

public CmsSolrResultList search(CmsObject cms,

 boolean ignoreMaxRows,
 javax.servlet.ServletResponse response,
 boolean ignoreSearchExclude,
 CmsResourceFilter filter,
 int maxNumResults)
                         throws CmsSearchException

Performs the actual search.

To provide for correct permissions two queries are performed and the response is fused from that queries:

1. a query for permission checking, where fl, start and rows is adjusted. From this query result we take for the response:
   • facets
   • spellcheck
   • suggester
   • morelikethis
   • clusters
2. a query that collects only the resources determined by the first query and performs highlighting. From this query we take for the response:
3. result
4. highlighting

Currently not or only partly supported Solr features are:

• groups
• collapse - representatives of the collapsed group might be filtered by the permission check
• expand is disabled

Parameters:

cms - the current OpenCms context

query - the OpenCms Solr query

ignoreMaxRows - true to return all requested rows, false to use max rows

response - the servlet response to write the query result to, may also be null

ignoreSearchExclude - if set to false, only contents with search_exclude unset or "false" will be found - typical for the the non-gallery case

filter - the resource filter to use

maxNumResults - the maximal number of results to search for

Returns:

the found documents
