            <title>[COMPASS-7606] Compass: Vector Search Hybrid Scoring</title>
                <link>https://jira.mongodb.org/browse/COMPASS-7606</link>
                <project id="13182" key="COMPASS">Compass </project>
                    <description>&lt;div class=&quot;panel&quot; style=&quot;background-color: #e3fcf7;border-color: #00684a;border-style: solid;border-width: 2px;&quot;&gt;&lt;div class=&quot;panelHeader&quot; style=&quot;border-bottom-width: 2px;border-bottom-style: solid;border-bottom-color: #00684a;background-color: #00684a;&quot;&gt;&lt;b&gt;Epic Summary&lt;/b&gt;&lt;/div&gt;&lt;div class=&quot;panelContent&quot; style=&quot;background-color: #e3fcf7;&quot;&gt;
&lt;h4&gt;&lt;a name=&quot;Summary&quot;&gt;&lt;/a&gt;Summary&lt;/h4&gt;

&lt;p&gt;Support result scoring based on combined results obtained from multiple search, vector-search and possibly non-search pipelines.&#160;&lt;/p&gt;

&lt;p&gt;Allow users to be able to use well known functions to combine scores (&lt;a href=&quot;https://docs.google.com/document/d/1EKV-mSDtR6PLvDzh3ayYljGK_t6L0RdP5IEPcESOLhQ/edit#heading=h.7nicyb6wlms3&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;like listed here)&lt;/a&gt;&#160;or to define custom score composition functions.&lt;/p&gt;
&lt;h4&gt;&lt;a name=&quot;Motivation&quot;&gt;&lt;/a&gt;Motivation&lt;/h4&gt;

&lt;p&gt;Users that have multiple search indexes (e.g. a regular search index and vector search index) may want to retrieve documents based on a score that depends on both vector distance and match quality to a regular search query.&lt;/p&gt;

&lt;p&gt;We want to provide a reasonably efficient and convenient way of obtaining a combining results from multiple pipelines that return documents with their respective scores.&#160;&lt;/p&gt;
