Tigase Message Archiving Component
Querying by tags

To search for hashtags or user names already used following request might be used:

<iq type="set" id="query2">
    <tags xmlns="http://tigase.org/protocol/archive#query" like="#test"/>
</iq>

which will return suggested similar hashtags which where found in database for particular user if following response:

<iq type="result" id="query2">
    <tags xmlns="http://tigase.org/protocol/archive#query" like="#test">
        <tag>#test1</tag>
        <tag>#test123</tag>
        <set xmlns="http://jabber.org/protocol/rsm">
             <first index='0'>0</first>
             <last>1</last>
             <count>2</count>
        </set>
    </tags>
</iq>
