Spelling correction performance is impacted by the size of the dictionary in use.

Spell-corrected keyword searches with many words, in systems with very large dictionaries, can take a disproportionately long time to process relative to other MDEX Engine requests. Those searches can cause requests that immediately follow such a search to wait while the spelling recommendations are being sought and considered.

Because of this, it is important to carefully analyze the performance of the system together with application requirements prior to production application deployment.

Consider also whether performance could be improved if you disable spelling correction on individual queries. For information about disabling spelling correction on individual queries, see the topic in this guide.
