Abstract: An apparatus may map one or more fields from a plurality of tables having a first table type to one or more mapped fields of a single table having a second table type and index the one or more mapped fields to correspond to a single index for the single table having the second table type. The apparatus may execute a first query using the single index corresponding to the one or more mapped fields to output a result for the first query. The apparatus may execute a second query for search activity that has occurred on the database since a last update to the single index and combine the result for the first query with the search activity that has occurred on the database since the last update to the single index to output a combined result based on the second query.

Abstract: An apparatus may receive, through a user interface, an input indicative of a document corpus from which to indicate trends of a document set. The document corpus may be one of a plurality of document corpuses included in the document set. The apparatus may filter the document corpus based on user-specific criteria to provide a filtered document corpus. The filtered document corpus includes a subset of documents from the document corpus. The apparatus may output an indication of the trends of the document set based on trending text of the filtered document corpus, where the trends of the document set correspond to the trending text of the filtered document corpus.
