                                <h1 id="rxquery">RxQuery</h1>
<p>A query allows to find documents in your collection.
Like most other noSQL-Databases, RxDB uses the <a href="https://github.com/cloudant/mango" target="_blank">mango-query-syntax</a>. It is also possible to use <a href="https://docs.mongodb.com/manual/reference/method/db.collection.find/#combine-cursor-methods" target="_blank">chained methods</a> with the <code>query-builder</code> plugin.</p>
<h2 id="find">find()</h2>
<p>To create a basic <code>RxQuery</code>, call <code>.find()</code> on a collection and insert selectors. The result-set of normal queries is an array with documents.</p>
<pre><code class="lang-js"><span class="hljs-comment">// find all that are older then 18</span>
<span class="hljs-keyword">const</span> query = myCollection
    .find({
      selector: {
        age: {
          $gt: <span class="hljs-number">18</span>
        }
      }
    });
</code></pre>
<h2 id="findone">findOne()</h2>
<p>A findOne-query has only a single <code>RxDocument</code> or <code>null</code> as result-set.</p>
<pre><code class="lang-js"><span class="hljs-comment">// find alice</span>
<span class="hljs-keyword">const</span> query = myCollection
    .findOne({
      selector: {
        name: <span class="hljs-string">&apos;alice&apos;</span>
      }
    });
</code></pre>
<pre><code class="lang-js"><span class="hljs-comment">// find the youngest one</span>
<span class="hljs-keyword">const</span> query = myCollection
    .findOne({
      selector: {},
      sort: [
        {age: <span class="hljs-string">&apos;asc&apos;</span>}
      ]
    });
</code></pre>
<pre><code class="lang-js"><span class="hljs-comment">// find one document by the primary key</span>
<span class="hljs-keyword">const</span> query = myCollection.findOne(<span class="hljs-string">&apos;foobar&apos;</span>);
</code></pre>
<h2 id="exec">exec()</h2>
<p>Returns a <code>Promise</code> that resolves with the result-set of the query.</p>
<pre><code class="lang-js"><span class="hljs-keyword">const</span> query = myCollection.find();
<span class="hljs-keyword">const</span> results = <span class="hljs-keyword">await</span> query.exec();
<span class="hljs-built_in">console</span>.dir(results); <span class="hljs-comment">// &gt; [RxDocument,RxDocument,RxDocument..]</span>
</code></pre>
<h2 id="query-builder">Query Builder</h2>
<p>To use chained query methods, you can use the <code>query-builder</code> plugin.</p>
<pre><code class="lang-ts">
<span class="hljs-comment">// add the query builder plugin</span>
<span class="hljs-keyword">import</span> { addRxPlugin } from <span class="hljs-string">&apos;rxdb&apos;</span>;
<span class="hljs-keyword">import</span> { RxDBQueryBuilderPlugin } from <span class="hljs-string">&apos;rxdb/plugins/query-builder&apos;</span>;
addRxPlugin(RxDBQueryBuilderPlugin);

<span class="hljs-comment">// now you can use chained query methods</span>

<h2 id="setting-a-specific-index">Setting a specific index</h2>
<p>By default, the query will be send to the RxStorage, where a query planner will determine which one of the available indexes must be used.
But the query planner cannot know everything and sometimes will not pick the most optimal index.
To improve query performance, you can specify which index must be used, when running the query.</p>

<h2 id="count">Count</h2>
<p>When you only need the amount of documents that match a query, but you do not need the document data itself, you can use a count query for <strong>better performance</strong>.
The performance difference compared to a normal query differs depending on which <a href="rx-storage.html">RxStorage</a> implementation is used.</p>
<pre><code class="lang-ts"><span class="hljs-keyword">const</span> query = myCollection.count({
  selector: {
    age: {
      $gt: <span class="hljs-number">18</span>
    }
  }

<span class="hljs-comment">// observe the result</span>

  <span class="hljs-built_in">console</span>.log(<span class="hljs-string">&apos;Currently has &apos;</span> + amount + <span class="hljs-string">&apos; documents&apos;</span>);
});
</code></pre>
<p><strong>IMPORTANT:</strong> count queries have a better performance than normal queries because they do not have to fetch the full document data out of the storage. Therefore it is <strong>not</strong> possible to run a <code>count()</code> query with a selector that requires to fetch and compare the document data. So if your query selector <strong>does not</strong> fully match an index of the schema, it is not allowed to run it. These queries would have no performance benefit compared to normal queries but have the tradeoff not not using the fetched document data for caching.</p>
<pre><code class="lang-ts"><span class="hljs-comment">/**

</code></pre>
<p>If you want to count these kind of queries, you should do a normal query instead and use the length of the result set as counter. This has the same performance as running a non-fully-indexed count which has to fetch all document data from the database and run a query matcher.</p>

<h2 id="notice-rxdb-will-always-append-the-primary-key-to-the-sort-parameters">NOTICE: RxDB will always append the primary key to the sort parameters</h2>
<p>For several performance optimizations, like the <a href="https://github.com/pubkey/event-reduce" target="_blank">EventReduce algorithm</a>, RxDB expects all queries to return a deterministic sort order that does not depend on the insert order of the documents. To ensure a deterministic ordering, RxDB will always append the primary key as last sort parameter to all queries and to all indexes.
This works in contrast to most other databases where a query without sorting would return the documents in the order in which they had been inserted to the database.</p>
<h2 id="notice-rxquerys-are-immutable">NOTICE: RxQuery&apos;s are immutable</h2>
<p>Because RxDB is a reactive database, we can do heavy performance-optimisation on query-results which change over time. To be able to do this, RxQuery&apos;s have to be immutable.
This means, when you have a <code>RxQuery</code> and run a <code>.where()</code> on it, the original RxQuery-Object is not changed. Instead the where-function returns a new <code>RxQuery</code>-Object with the changed where-field. Keep this in mind if you create RxQuery&apos;s and change them afterwards.</p>
<p>Example:</p>
<pre><code class="lang-javascript"><span class="hljs-keyword">const</span> queryObject = myCollection.find().where(<span class="hljs-string">&apos;age&apos;</span>).gt(<span class="hljs-number">18</span>);
