Improve Relevance Of Results By Adding Scoring Profiles

How Search Scores Are Calculated ?

The final stage of processing a search query is scoring. The documents that are retrieved from the first three stages are ranked by the search engine. The number of times detected search phrases exist in a document, the size of the document, and the rarity of each keyword all affect the score. The search results are automatically sorted by search score, with the highest score appearing first. An $orderby clause can be included to break a tie between two documents that have the same search score.

Improve Score For More Relevant Documents

The final score may not be the highest for the most relevant document because the default scoring is based on phrase frequency and rarity. Because every dataset is unique, AI Search allows you to use scoring profiles to affect a document's score.

The most straightforward scoring profile defines different weights for fields in an index. Functions like freshness and distance can also be included in the score profile. Compared to basic weighting, functions offer greater control. For instance, you may specify how long younger papers will be boosted before they receive the same score as older documents.

Because of the power of scoring profiles, you can apply a scoring profile to an index so that fields are automatically raised for all queries, rather than boosting a particular phrase in a search request.

Add Weighted Scoring Profile

You can add up to 100 scoring profiles to a search index. The simplest way to create a scoring profile is in the Azure portal.

  • Navigate to your search service.

  • Select Indexes, then select the index to add a scoring profile to.

  • Select Scoring profiles.

  • Select + Add scoring profile.

  • In Profile name, enter a unique name.

  • To set the scoring profile as a default to be applied to all searches select Set as default profile.

  • In Field name, select a field. Then for Weight, enter a weight value.

  • Select Save.

You can control which scoring profile is applied to a search query by appending the &scoringProfile=PROFILE NAME parameter.

Scoring profiles can also be added programmatically using the Update Index REST API or in Azure SDKs, such as the ScoringProfile class in the Azure SDK for .NET.

Connect Data to Azure Sentinel Using Data Connectors

  Ingest Log Data with Data Connectors You should connect your data sources with Azure Sentinel Connectors to collect the log data whose page displays a growing list of the connectors provided by Azure Sentinel, after selecting the Open connector page (the detailed connector page has a left and right blade).  The information about the connector, the connector's status, and the last time a log was received if connected is provided by the left blade. Whereas the right tab has two tabs- Instructions and Next Steps. The instructions tab can be different based on the connector having Prerequisites and Configuration which can be followed to connect to the data source. The Next Steps tab offers a quick reference to workbooks, query samples, and analytical templates. Data connectors can only be disconnected/deactivated, not deleted. Note-  The connector does not install Workbooks and Analytical Templates as they are already available in the Sentinel environment for out of the box...

  About If you are experiencing problems with the Microsoft Purview Information Protection scanner, check the health of your deployment by utilizing the Start-ScannerDiagnosticsPowerShell cmdlet to start the scanner diagnostic tool. The diagnostics tool checks the following details and then creates a log files with the results: Whether the database is up to date. Whether network URLs are accessible. Whether there's a valid authentication token and policy can be acquired. Whether the profile is defined in the Azure portal. Whether offline/online configuration exists and can be acquired. Whether the rules configured are valid.  The Start-ScannerDiagnostics command does not perform a comprehensive check of prerequisites. If you encounter problems with the scanner, you need to verify that your system meets the scanner's requirements, and that your scanner's configuration and installation are finished.  Verify Scanning Details Per Scanner Node and Repository Run the Get-ScanSt...

  Introduction Azure AI Search is a service that allows to reliably extract content search, extract, and understand at scale. It is typically used to search for documents, data surveys, and chat-style Copilot apps over proprietary data. Indexing and querying are Azure AI Search's two main workloads. While querying allows to search the content from index, indexing loads the content into the search engine and makes it searchable. By connecting to one of the Azure AI Search indexes from within Copilot, the Microsoft Security Copilot integration for Azure enables to use the content in Copilot to produce contextualized, pertinent, and targeted responses.  Requirement Before using the Azure AI Search plugin in Copilot, the desired Azure AI Search index to connect to Copilot is configured as follows: The text field must be searchable.  The title field must be filterable. The vector-field must use text-embedding-ada-002. Integrated vectorization can be used to setup an index in t...
