+     <section id="preamble" aria-label="Preamble"><p>Streaming expressions provides a powerful set of functions for transforming result sets.
+This section of the user guide provides an overview of useful transformations applied to result sets.</p></section>
+<section class="sect1"><h2 id="selecting-and-adding-fields">Selecting and Adding Fields</h2><p>The <code>select</code> function wraps another streaming expression can perform the following operations on each tuple
+in the stream:</p>
+<div class="ulist"><ul><li><p><strong>Select</strong> a subset of fields</p></li><li><p><strong>Map</strong> fields to new names</p></li><li><p><strong>Compute</strong> new fields</p></li></ul></div>
+<p>Below is an example showing the <code>select</code> function wrapping a <code>search</code> function
+and mapping fields to new field names. The <code>recNum</code> function is a math expression
+which simply returns the current record number of the tuple. The <code>select</code> expression can call
+any math expression to compute new values.</p>
+<div class="imageblock"><img src="images/math-expressions/select1.png" alt="select1"></div>
+<p>Below is an example using the <code>div</code> function to compute a new field
+from two existing fields:</p>
+<div class="imageblock"><img src="images/math-expressions/select-math.png" alt="select math"></div></section>
+<section class="sect1"><h2 id="filtering-tuples">Filtering Tuples</h2><p>The <code>having</code> function can be used to filter tuples in the stream based on
+boolean logic.</p>
+<p>In the example below the <code>having</code> function is filtering the output of the
+<code>facet</code> function to only emit tuples that have <code>count(*)</code> greater than 20404.</p>
+<div class="imageblock"><img src="images/math-expressions/having.png" alt="having"></div></section>
+<section class="sect1"><h2 id="paging">Paging</h2><p>The <strong>record number</strong>, added with the <code>recNum</code> function,
+can be filtered on to support paging.</p>
+<p>In the example below the <code>and</code> function with nested <code>lt</code> and <code>gt</code> functions are
+used to select records within a specific record number range:</p>
+<div class="imageblock"><img src="images/math-expressions/search-page.png" alt="search page"></div></section>
+<section class="sect1"><h2 id="handling-nulls">Handling Nulls</h2><p>The <code>notNull</code> and <code>isNull</code> functions can be used to either replace null values with different values,
+or to filter out tuples with null values.</p>
+<p>The example below is using the <code>isNull</code> function inside of <code>select</code> function
+to replace null values with -1. The <code>if</code> function takes 3 parameters. The first
+is a boolean expression, in this case <code>isNull</code>. The <code>if</code> function returns
+the second parameter if the boolean function returns true, and the third
+parameter if it returns false. In this case <code>isNull</code> is always true because its
+checking for a field in the tuples that is not included in the result set.</p>
+<div class="imageblock"><img src="images/math-expressions/select2.png" alt="select2"></div>
+<p><code>notNull</code> and <code>isNull</code> can also be used with the <code>having</code> function to filter out
+tuples with null values.</p>
+<p>The example below emits all the documents because it is evaluating <code>isNull</code> for
+a field that is not in the result set, which always returns true.</p>
+<div class="imageblock"><img src="images/math-expressions/having2.png" alt="having2"></div>
+<p>The example below emits zero documents because it is evaluating <code>notNull</code> for
+a field that is not in the result set, which always returns false.</p>
+<div class="imageblock"><img src="images/math-expressions/having3.png" alt="having3"></div></section>
+<section class="sect1"><h2 id="regex-matching-and-filtering">Regex Matching and Filtering</h2><p>The <code>matches</code> function can be used inside of a <code>having</code> function
+to test if a field in the record matches a specific
+regular expression. This allows for sophisticated regex matching over search results.</p>
+<p>The example below uses the <code>matches</code> function to return all records where
+the <code>complaint_type_s</code> field ends with <strong>Commercial</strong>.</p>
+<div class="imageblock"><img src="images/math-expressions/search-matches.png" alt="search matches"></div></section>
+<section class="sect1"><h2 id="sorting">Sorting</h2><p>The <code>sort</code> and <code>top</code> function can be used to resort a result set in memory. The <code>sort</code> function
+sorts and returns the entire result set based on the sort criteria. The <code>top</code> function
+can be used to return the top N values in a result set based on the sort criteria.</p>
+<div class="imageblock"><img src="images/math-expressions/search-resort.png" alt="search resort"></div></section>
+<section class="sect1"><h2 id="rollups">Rollups</h2><p>The <code>rollup</code> and <code>hashRollup</code> functions can be used to perform aggregations over result sets. This
+is different then the <code>facet</code>, <code>facet2D</code> and <code>timeseries</code> aggregation functions which push the aggregations
+into the search engine using the JSON facet API.</p>
+<p>The <code>rollup</code> function performs map-reduce style rollups, which requires the result stream be sorted by the
+the grouping fields. This allows for aggregations over very high cardinality fields. The <code>hashRollup</code> function
+performs rollups keeping all buckets in an in-memory hashmap. This requires enough memory to store all the
+distinct group by fields in memory, but does not require that the underlying stream be sorted.</p>
+<p>The example below shows a visualization of the top 5 complaint types
+from a random sample of the <code>nyc311</code> complaint database. The <code>top</code>
+function is used to select the top 5 complaint types based on
+the <code>count(*)</code> field output by the <code>hashRollup</code>.</p>
