   <p>
       A simple Cloudant output node. Stores <b>msg</b> in a chosen database.
    </p>
   <p>
       Cloudant generates a random id for the <code>_id</code> property if one
       is not specified and a new document will be <b>inserted</b> each time.
       You can <b>insert</b> only the <code>msg.payload</code> by checking the
       checkbox in the configuration window.
   </p>
   <p>
       If you want to <b>update</b> an existing document you must specify the
       latest values for <code>_id</code> and <code>_rev</code> in your object.
       If they don't match the current values stored in the database you will
       receive a <b>conflict error</b> message, so make sure you are using the
       most updated information for the document.
    </p>
    <p>
        It is also possible to <b>delete</b> documents from the database by
        providing values for <code>_id</code> and <code>_rev</code> and selecting
        the <b>remove</b> option for the node. You can pass these values in the
        <code>msg</code> object itself or as an object in the
        <code>msg.payload</code>.
    </p>
    <p>
        The <b>database name</b> must follow these rules:
        <ul>
            <li>No spaces</li>
            <li>All letters in small caps</li>
            <li>The first character can't be <code>_</code></li>
        </ul>
    </p>
    <p>
        Your document should avoid having top-level fields that start with
        <code>_</code>, with exceptions for <code>_id</code>, <code>_rev</code>
        and other <a href="https://wiki.apache.org/couchdb/HTTP_Document_API#Special_Fields">
        CouchDB reserved words</a>.
    </p>
</script>

<script type="text/x-red" data-help-name="cloudant in">
   <p>
        A node for searching documents in a Cloudant database.
    </p>
    <p>
        Searching for documents can be done in three modes: directly by using the
        document's <b>_id</b>, by using an existing <a
        href="https://cloudant.com/for-developers/search/" target="_blank">Search
        Index</a> or retrieving <b>all documents</b> stored in your database.
    </p>
    <p>
        When querying using the <b>_id</b> option, the value for the document's
        <code>_id</code> should be passed in the <code>msg.payload</code> as a
        string.
    </p>
    <p>
        To use an existing <b>Search Index</b> stored on the desired database,
        the query argument should be passed on the <code>msg.payload</code> as a
        string following the <code>indexName:value</code> pattern. Keep in mind
        that <i>the index must be created beforehand in the database.</i> and
        referenced here by its <code>design document/index name</code>.
    </p>
    <p>
        When querying using a <b>Search Index</b> you can pass the search
        parameters as an object in <code>msg.payload</code>.
    </p>
    <p>
        For example, you can pass an object like this:
    <p>
        <code>{ query: "abc*", limit: 100 }</code>
    </p>
    <p>
        to change the value of <code>limit</code>. You can find more information
        about <b>Search Index</b> parameters in the <a
        href="https://docs.cloudant.com/api.html?http#queries" target="_blank">
        official Cloudant documentation</a>.
    </p>
    <p>
        The last method to retrieve documents is to simply get all of them by
        selecting the option <b>all documents</b>.
    </p>
    <p>
        The <b>database name</b> must follow these rules:
        <ul>
            <li>No spaces</li>
            <li>All letters in small caps</li>
            <li>The first character can't be <code>_</code></li>
        </ul>
    </p>
