<p>
<a class="link" href="DeeIndex.html" title="DeeIndex"><span class="type">DeeIndex</span></a> is an interface for doing key based access to a <span class="type">DeeModel</span>.
A key in the index is known as a <span class="emphasis"><em>term</em></span> and each term is
mapped to a set of matching <a class="link" href="dee-1.0-DeeModel.html#DeeModelIter"><span class="type">DeeModelIter</span></a>s.
</p>
<p>
The terms are calculated by means of a <a class="link" href="DeeAnalyzer.html" title="DeeAnalyzer"><span class="type">DeeAnalyzer</span></a> which extracts a set of
terms from a given row in the model adding these terms to a <a class="link" href="DeeTermList.html" title="DeeTermList"><span class="type">DeeTermList</span></a>.
There is a suite of analyzers shipped with Dee, which you can browse in the
Analyzers section.

Be cautious if you plan on modifying the rows in the model via the
DeeModelIters you find. Your code may have to be reentrant since
the index may change in reaction to the changes in the model. It's not
impossible to do this in a non-broken manner, but it may likely require
you calling <code class="function">dee_model_freeze_signals()</code> and <code class="function">dee_model_thaw_signals()</code> at
strategic points.

Convenience function in for cases where you have a priori guarantee that
a <a class="link" href="DeeIndex.html#dee-index-lookup" title="dee_index_lookup ()"><code class="function">dee_index_lookup()</code></a> call will return exactly 0 or 1 row. If the lookup
returns more than 1 row a warning will be printed on standard error and
<code class="literal">NULL</code> will be returned.
</p>
<p>
The typical use case for this function is if you need something akin to
a primary key in a relational database.
