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 prior to production application deployment.
