\n\n**Timeout period in seconds for AI Search node health status check request** \\(**glide.ais.monitor.health\\_status\\_check\\_timeout**\\)\n\n\n\nTimeout period in seconds for AI Search partition health status checks.- Type: integer\n- Default value: **30**\n- Location: **System Properties** > **AI Search** \\(AI Search Monitor Properties section\\)\n\n
\n\n**Inclusive lower bound for GREEN \\(healthy\\) range of AI Search node health scores** \\(**glide.ais.monitor.health\\_threshold\\_green**\\)\n\n\n\nInclusive lower percentage bound for green partition health score range. The inclusive upper bound for this health score range is 100.- Type: integer\n- Default value: **90**\n- Location: **System Properties** > **AI Search** \\(AI Search Monitor Properties section\\)\n\n
\n\n**Inclusive lower bound for YELLOW range of AI Search node health scores** \\(**glide.ais.monitor.health\\_threshold\\_yellow**\\)\n\n\n\nInclusive lower percentage bound for yellow partition health score range. The non-inclusive upper bound for this health score range is set by the **glide.ais.monitor.health\\_threshold\\_green** property value. The red partition health score range includes all scores below this property value. If the health score for an active partition drops into the red range, and if **glide.ais.ha.enable\\_auto\\_failover** is set to **true**, AI Search failover on the partition.\n\n- Type: integer\n- Default value: **50**\n- Location: **System Properties** > **AI Search** \\(AI Search Monitor Properties section\\)\n\n
\n\n**Maximum request count per search query for AI Search node** \\(**glide.ais.query.max\\_request\\_count\\_per\\_search**\\)\n\n\n\nMaximum number of requests that an AI Search node can process per search query.- Type: integer\n- Default value: **10**\n- Location: **System Properties** > **AI Search** \\(AI Search Query Properties section\\)\n\n
\n\n**Search query result count multiplier for AI Search node** \\(**glide.ais.query.requested\\_rows\\_multiplier**\\)\n\n\n\nResult-count multiplier for search queries that use the late binding security implementation. The system multiplies the search query's minimum desired result count by this factor before requesting records from the AI Search node. Extra records replace any search results removed by the late-binding security implementation. For example, with the default value of **3**, a search query that uses the late binding security implementation and expects at least 10 results produces a request to the AI Search node for 30 matching records. The final result set includes the first 10 of these records that the user can access.\n\n Lower values improve search query performance but may reduce the search result count below the requested minimum.\n\n- Type: integer\n- Default value: **3**\n- Location: **System Properties** > **AI Search** \\(AI Search Query Properties section\\)\n\n
\n\n**Boolean search operator to use when a search query includes multiple terms** \\(**glide.ais.query.search\\_operator**\\)\n\n\n\nBoolean search operator to use when a search query includes multiple terms. When using the AND \\(conjunctive\\) operator, search only finds records that include all search query terms and phrases. When using the OR \\(disjunctive\\) operator, search finds records that include any search query term or phrase.\n\n- Type: string\n- Default value: **AND then OR 2+ key terms**\n- Supported values:\n - **AND then OR 2+ key terms**: Search using the AND operator. If the search query contains more than two search terms after stop word removal and returns less than one full page of results, automatically resubmit it using the OR operator.\n\nThe resubmitted search query only finds records that contain at least half \\(rounded up\\) of the terms and phrases in the OR expression.\n\n**Note:** When you view the **glide.ais.query.search\\_operator** record on the System Property \\[sys\\_properties\\] table, this value appears as **AND\\_OR\\_ENHANCED**.\n\n - **AND then OR query**: Search using the AND operator. If the search query returns less than one full page of results, automatically resubmit it using the OR operator.\n\nThe resubmitted search query only finds records that contain at least half \\(rounded up\\) of the terms and phrases in the OR expression.\n\n**Note:** When you view the **glide.ais.query.search\\_operator** record on the System Property \\[sys\\_properties\\] table, this value appears as **AND\\_OR**.\n\n - **OR query**: Search using the OR operator.\n - **AND query**: Search using the AND operator.\n\n**Note:** This value is not displayed on the AI Search system properties page, but can be set when editing the **glide.ais.query.search\\_operator** record on the System Property \\[sys\\_properties\\] table.\n\n- Location: **All** > **System Properties** > **AI Search** \\(AI Search Query Properties section\\)\n\n
\n\n**Force AI Search to use late binding for ACL evaluation** \\(**glide.ais.security.force\\_late\\_binding**\\)\n\n\n\nOption to force use of the late binding security implementation for all search queries. For descriptions of the early binding and late binding security implementations, see [Content security in AI Search](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/ai-search/content-security-ais.md).\n\n- Type: true \\| false\n- Default value: **false**\n- Supported values:\n - **true**: The system uses the late binding security implementation for all search queries.\n - **false**: The system uses the early binding security implementation for search queries. If search results include scripted ACLs, or if early binding encounters an error, the system switches to use the late binding security implementation.\n- Location: **System Properties** > **AI Search** \\(AI Search Security Properties section\\)\n\n**Note:** You can enable the late binding security implementation for all search results from a particular indexed source by setting the **Force Late Binding** field to **true** for the indexed source.\n\n
\n\n**Enable global language fallback** \\(**glide.ais.translate.enable\\_global\\_language\\_fallback**\\)\n\n\n\nOption to enable matching of translated documents in the instance locale's language as well as the user's session language. For example, suppose a user searches from a Japanese user session on an instance with the default US English locale. With the default system property value of **false**, this search only matches knowledge articles in Japanese. If the system property value is set to **true**, the same search matches articles in both Japanese and English.\n\n To learn more about translated document matching, see [Searching translated content](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/ai-search/searching-translated-content-ais.md). For details on instance locales, see [Configuring locales](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/system-localization/c_DefineLocales.md).\n\n - Type: true \\| false\n- Default value: **false**\n- Supported values:\n - **true**: AI Search matches translated documents in the instance locale's language as well as the user's session language.\n - **false**: AI Search only matches translated documents in the user's session language.\n- Location: **System Properties** > **AI Search** \\(AI Search Multi-Language Support section\\)\n\n
\n\n**glide.mlpredictor.ml\\_x\\_snc\\_global\\_global\\_6eedb38234bf5010f877396127c8ffee.predict.request\\_timeout**\n\n\n\nTimeout period for ML predictions used in Genius Result processing. If Genius Result processing time exceeds this value for a search query, no Genius Result answers are displayed in the search query results.\n\n- Type: integer\n- Default value: **1000**\n- Location: System Properties \\[sys\\_properties\\] table\n\n
\n\n**query.maxDictionaryTermLength**\n\n\n\nCharacter length limit for stop word and synonym dictionary terms. AI Search ignores dictionary terms that exceed this length limit.- Type: integer\n- Default value: **256**\n- Location: System Properties \\[sys\\_properties\\] table\n\n
