Performance impact for Spelling Correction and Did You Mean

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 Oracle Endeca Server requests. Those searches can cause requests that immediately follow such a search to wait while the spelling recommendations are being sought and considered.

It is important to carefully analyze the performance of the system together with application requirements before deploying a production application.
