There is not a silver bullet solution. More handles you allow more memory is consumed by it and few more CPU cycles are possibly wasted in maintaining those handles. The low number set by default by most of the systems is just a precaution to detect leaks of the handles by applications soon enough and it is safe to increase the number as necessary if you know the cause of the issue and are sure that it is not a leak.
The fact that you got the error while indexing the content doesn't necessarily mean that the indexer is the cause of the problem (just the unlucky to be the first one requesting file handle when none were left). Maybe you are using data store or keeping your blobs in FS as well? Or maybe it is the indexer ... can you look how many subdirectories and files you have in the index subfolder of each workspace (total count incl. sub dirs) IF you have too many in one of the workspaces you can fine tune the SearchIndexer configuration in your workspace.xml. The parameters you would want to change are maxMergeDocs and mergeFactor. MaxMergeDocs controls how many "documents" (not real files, just what Lucene considers doc in a JR context) are merged together, so you might want to increase this value to reduce the number of index files created. Side effects are two: larger index file means more efficient query but also longer time to generate the index (e.g. it takes longer before newly added content becomes searchable). The default 100000 is supposed to be optimal in most cases. The mergeFactor controls how many index files are compiled into the segment ... more files in a segment longer it takes to search the segment, the slower the search will be. Default value is 10. If you change any of those values you need to delete index in given workspace and regenerate it.
