Executing a tijah query in a module from both old and new front ends 
fails.
What is the problem when you execute the same tijah function with the
default frontend?
...
Using the old front end (\g) produces the following error:
Would you please attach the file 'tj.xq' so that we also can run your
query with both frontends (assuming the small/simplified document you
sent in your previous e-mail is still sufficient to run the query).

Has anyone succeeded in executing a tijah query from within a module?
I ran your tijahSearch() on a windows vista 64bits, without xrpc, with
both frondends, and I got similar errors.
So, it looks like a Tijah related problem, not xrpc related problem.
I'm not familiar with Tijah queries, so I'd like to recommend you to run
your query without xrpc to see what happens exactly on your system, and
report the errors, so that the tijah experts could have a look at your
problem.
If I run the query from the command line within mclient using the 
default front end (\G) it works fine, i.e:
xquery>tijah:queryall("//speech[about(., Heathrow)]")
...
...
The error using the default front end (\G) is:
xquery>import module namespace test="tj" at
    "http://localhost:50001/export/tj.xq
    ";
    more>execute at {"localhost"} {test:tijahSearch("Heathrow")}

            !ERROR: interpret_params: reverse(param 1): evaluation error.

This is because xrpc doesn't work with the default frond end.

Yes, as you stated elsewhere. I was just responding to your request for 
the error when using the default front end. I don't know if it's 
signficant but I see that the error from both the old and default front 
ends includes a reference to: "no matching MIL operator..."

So the state of play seems to be this: since tijah does not work using 
the old front end (see above), it isn't going to work via xrpc which is 
using the old front end.
