A searchable index is created using a query process and an indexing process. The query process cooperates with the indexing process to catalogue items that are located within a specified search scope. Previously indexed items are evaluated to ensure that their indexes are up-to-date. Items that are out-of-date have unreliable indexes that should be updated. Items to be indexed within the specified search scope are grouped in batches for processing. As processing of each batch is completed their respective indexing results become available such that partially indexed search scopes are useable while the indexing process continues. Since indexing results trickle in on an ongoing basis, users are permitted to process and/or view indexing results without waiting for the complete indexing process to be completed.
