Problems with Lucene and setLimit/setLimitBy

[alr]

Hello,

I am currently investigating a problem, where I want to limit the amount of returned results, when performing (and sorting) a lucene search. This is what I do in the source:

SearchParameters sp = new SearchParameters();
sp.addStore(storeRef);
sp.setLanguage(SearchService.LANGUAGE_LUCENE);
sp.setLimitBy(LimitBy.FINAL_SIZE);
sp.setLimit(limit);
sp.addSort(sortField, sortAscending);
sp.setQuery(searchString);

ResultSet resultSet = searchService.query(sp);
List<NodeRef> refs = resultSet.getNodeRefs();
        
if (logger.isDebugEnabled()) {
    ResultSetMetaData metaData = resultSet.getResultSetMetaData();
    logger.debug("Search has been limited by " + metaData.getLimitedBy() + ". # of results: " + refs.size());
    logger.debug("SP GetLimit: " + metaData.getSearchParameters().getLimit() + " and limitby " + metaData.getSearchParameters().getLimitBy());
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Now this is the logger output:

16:48:07,330 User:admin DEBUG [alfresco.search.MySearchImpl] Search has been limited by UNLIMITED. # of results: 108
16:48:07,330 User:admin DEBUG [alfresco.search.MySearchImpl] SP GetLimit: 101 and limitby FINAL_SIZE
‍‍‍‍

So, somehow, my limit settings are completely ignored. I get 108 results returned. In case you wonder, why I set the limit to 101, take a look at org.alfresco.service.cmr.search.ResultSetMetaData, where is written in the comments, that searches for an amount lower than 100, might return LimitBy.UNLIMITED. However in this case the search does it as well (sorting works btw).

So, is there anything I am overlooking right now, or didn't I parse the ResultSet correctly? Do I need to access filtered results in another way?

I am using Alfresco Labs 3b, btw.

Thanks for the help!

Hi,

If you can set a breakpoint in the ACLEntryAfterInvocationProvider class, it seems there are strange things done in the decide method that accepts a ResultSet as last argument.

Hi

Setting a breakpoint there does not result in any break. I set the breakpoint at the beginning of the

private ResultSet decide(Authentication authentication, Object object, ConfigAttributeDefinition config,
            ResultSet returnedObject) throws AccessDeniedException

Method. The only on referring ResultSet as parameter.

I am currently calling that particular search operation from a Trigger - could that be a problem?

Hi,

What do you mean by Trigger ? Are you using searchService will an upper S or lower s ?
