Hi, To avoid such a delay, add a "Start Date" to your query. This will limit the range of records that are searched. This is recommended, because when performing a search on a phone number, NowSMS does not look for an exact match on the phone number, instead it is looking for a substring match, which will force the database manager to scan all records for this data. In other words, if you search for 0000, it will match 0000, 0000123, 70000, 8880000777, etc. (SQL clause LIKE '%0000%') Specifying a "Start Date" will limit the number of records that are searched. (By comparison, max log entries=1000 limits the number of matching entries that will be returned, not the number that are searched.) Your report is making us reconsider this behaviour in future releases, as querying for a specific phone number tends to be a frequent task. We are considering adding a database index to the From/To numbers, and searching for an exact match, which would be extremely fast. However, for now, please add a "Start Date" to limit the search range. Regards, Des NowSMS Support | |||
