Summary
When using the repository's search function to look within a specific folder, the search can take a long time if there are many entries in the folder. You can insert a special database option to make the search faster. This only applies to Laserfiche Server 10.2.1 and later.
To make within-folder searches inside folders with many entries faster
Insert into DBOPTIONS values('SearchLookinThreshold','0').
Note: Setting SearchLookinThreshold to 0 can slow down within-folder searches when those folders have very few entries.
