+# Description
+Over time, your code spreads across dozens of artifact types and it becomes very difficult to keep track of it all. 
+
+The whole thing is made more difficult by the fact that JavaScript code is not always contained in pure script fields but also, for example, in conditions or even in JSON payloads. 
+
+Fortunately, there is a code search - for example in the ServiceNow Studio, via the UI page "CodeSearchExampleUse" or with the help of the browser extension "SN Utils".
+
+However in a baseline instance the code search covers about 31 tables and their fields only. If you want to search all available tables and script-related fields, you can execute my script `add_more_tables_to_code_search`. It determines in the dictionary all potential candidates that could hold JavaScript code and add them to the code search base.
+
+# Involved tables
+
+## `sn_codesearch_search_group`
+
+A search group has a certain name and covers all tables and fields which can be searched when using that search group. Utilizing "SN Utils" browser extension you can select the preferred search group. Within ServiceNow Studio this is not possible and the search group "sn_devstudio.Studio" is leveraged automatically. For this reason my script adds all tables and fields to all search groups the same way.
+
+## `sn_codesearch_table`
+
+Each record in that table represent a table and their fields which are searchable. These records are added or complemented by my script.
+
