Enable or disable the Zing junk filter
When its junk filter is enabled, Zing doesn't index or search for 2-digit numbers or single-character words (unless they are Chinese or Japanese characters). You can enable or disable the junk filter for individual tables.
Before you begin
Role required: admin
About this task
For example, to disable matches for search terms like a or 40 in the Knowledge Base, turn on junk filtering for the kb_knowledge table.
Procedure
-
Navigate to All > System Definition > Dictionary.
-
Open the dictionary entry for the table.
-
In the Attributes related list, set the value of the Text index filter junk attribute:
-
If you want Zing to include 2-digit numbers and single-character words when indexing and searching the table, set the attribute value to
false. -
If you want Zing to ignore 2-digit numbers and single-character words when indexing and searching the table, set the attribute value to
true.
-
-
Select the additional actions icon [Omitted image "polaris-ui-form-context-menu-icon.png"] Alt text: in the Dictionary Entry form header, then select Save.
-
Select the Generate Text Index related link and select OK.
Note:
- To have the desired effect, you may also need to reconfigure the automatic stop words. For example, if a specific 2-digit number appears in all of your problem numbers (92-0001, 92-0002, and so on), the automatic stop word threshold is quickly exceeded and the word is no longer found in searches. To find that 2-digit number in the problem table, you must disable both junk filtering and automatic stop words.
- Disabling the junk filter results in a larger table index. For optimal performance, don't apply this attribute unless it's required.

# Enable or disable the Zing junk filter
When its junk filter is enabled, Zing doesn't index or search for 2-digit numbers or single-character words \(unless they are Chinese or Japanese characters\). You can enable or disable the junk filter for individual tables.
## Before you begin
Role required: admin
## About this task
For example, to disable matches for search terms like `a` or `40` in the Knowledge Base, turn on junk filtering for the kb\_knowledge table.
## Procedure
1. Navigate to **All** > **System Definition** > **Dictionary**.
2. Open the dictionary entry for the table.
3. In the Attributes related list, set the value of the **Text index filter junk** attribute:
1. If you want Zing to include 2-digit numbers and single-character words when indexing and searching the table, set the attribute value to `false`.
2. If you want Zing to ignore 2-digit numbers and single-character words when indexing and searching the table, set the attribute value to `true`.
4. Select the additional actions icon \[Omitted image "polaris-ui-form-context-menu-icon.png"\] Alt text: in the Dictionary Entry form header, then select **Save**.
5. Select the **Generate Text Index** related link and select **OK**.
**Note:**
- To have the desired effect, you may also need to reconfigure the [automatic stop words](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/search-administration/t_ConfigureAnAutomaticStopWord.md). For example, if a specific 2-digit number appears in all of your problem numbers \(92-0001, 92-0002, and so on\), the automatic stop word threshold is quickly exceeded and the word is no longer found in searches. To find that 2-digit number in the problem table, you must disable both junk filtering and automatic stop words.
- Disabling the junk filter results in a larger table index. For optimal performance, don't apply this attribute unless it's required.
