Set the Auto Flush parameter to limit the age of search strings used to create auto-complete suggestions and search suggestions.

## Before you begin

Role required: admin

## About this task

The Search Event \[sys_search_event\] table contains all of the strings used in searches. Scripts use this table to generate search analytics, search suggestions, and auto-complete suggestions. A system property sets the maximum
age for records preserved in the table. The default is 180 days, but you can change this number to preserve search events for a shorter or longer duration. Longer durations increase the size of the table and its disk
consumption.

## Procedure

1. Navigate to the Auto Flush \[sys_auto_flush\] table's list view.
   1. Select All.
   2. In the Filter field, enter <kbd class="ph userinput">sys_auto_flush.list</kbd>.
   3. Press Enter.
   {#set-maximum-number-of-search-strings__substeps_htg_ff5_b1c}
2. Search on <kbd class="ph userinput">*search</kbd> and open the sys_search_event record.
3. On the Auto Flush form, edit the Age in seconds value.  
   The default is 15,552,000 seconds, which is 180 days.
