Hi, Varun:
Your use case sounds very similar to the one given in the documentation:
http://docs.marklogic.com/guide/search-dev/alerts#id_71547
In summary:
* The serialized query in the rule should match the topic keywords.
* The metadata in the rule should contains the list of users who have
registered an interest in the topic.
* The action should read the metadata and send the email.
* The configuration should fire the alerts for new or changed documents.
In this approach, you won't need to update a list of new documents.
You will need to keep a separate document mapping topic keywords to users, but
you planned to do that anyway. The only difference is that you should put each
topic in a separate document rather than in one document.
(In general, in working with MarkLogic, it's better to put each record in a
separate document and aggregate as needed rather than put all records in a
single document and extract as needed.)
Hoping that helps,
Erik Hennum

Subject: Re: [MarkLogic Dev General] cts:reverse-query
Hello Charles,
Thanks for reply...
Charles if I will create a document for each keyword then again it becomes same
problem as I facing with current solution.
Any other way to short out this problem from ML side.
Thanks,
Varun

Hi Varun,
With reverse-query what you want to do is actually store the cts:query of
interest within a document. The query has to be serializable. Then reverse
query will return the document which contains a query that matches doc.xml.
So typically, you'd create a separate document for each keyword, which would
look something like:
<query>
<cts:word-query xmlns:cts="http://marklogic.com/cts";>
<cts:text xml:lang="en">
[email protected]<mailto:[email protected]>
</cts:text>
</cts:word-query>
</query>
I made this by evaluating
<query>{cts:word-query("[email protected]"<mailto:[email protected]>)}</query>
Then, when I run something like
cts:search(/, cts:reverse-query(<doc>My name is
[email protected]<mailto:[email protected]></doc>))
then the stored <query> doc above is returned.

Hello All,
As I want to create an alert API. In which I am using two xml files say
user_id.xml and doc.xml .
The format of user_id.xml is like this
<data>
<keyword name="MarkLogic">
<mail>[email protected]<mailto:[email protected]></mail>
<mail>[email protected]<mailto:[email protected]></mail>
<mail>[email protected]<mailto:[email protected]></mail>
<mail>[email protected]<mailto:[email protected]></mail>
</keyword>
<keyword name="google">
.........
.........
</keyword>
</data>
Another file doc.xml contains all the recent document name inserted into my
ML database.
Now, for each new document (those are present in doc.xml ) I want to do a
reverse query on the user_id.xml so that If the new document contains the
keyword(which is in user_id.xml)
then mail can be send to all the email-id under that keyword.
Right now I have implemented this using simple search method which for each
document and for each keyword I am applying cts:contains and if it returns
true then I am sending mails
to all the emails under that keyword.
But this method will not work if we have large set of keywords with huge
no. of users.
So, suggest me how can I use cts:reverse-query to implements this.
Thanks.
