Dear all,
We are trying to do a full text search in a database, but we can use some help
to get started. A small excerpt from our database is stated below:
//===
xquery>doc("ep")
<?xml version="1.0" encoding="utf-8"?>
<eprintsdata xmlns="http://eprints.org/ep2/data";>
<record>
<field name="eprintid">629</field>
<field name="keywords">Model-based on-the-fly Testing, Timed Automata,
Real-Time Testing, TorX, Tools.</field>
<field name="research_projects">STRESS: Systematic Testing of Real-time
Software Systems</field>
</record>
<record>
<field name="eprintid">642</field>
<field name="keywords">Compositional modelling, supervisory control</field>
<field name="research_projects">HYBRIDGE: Distributed Control and Stochastic
Analysis of Hybrid Systems Supporting Safety Critical Real-Time Systems
Design</field>
</record>
</eprintsdata>
//===
The PF/Tijah Getting Started page
(http://dbappl.cs.utwente.nl/pftijah/Documentation/GettingStarted) mentions we
can do a full text query as follows:
let $c := collection("MyCollection")
for $res in tijah:query($c, "//html[about(., ir db)]")
return $res/head/title
I believe this way is probably outdated, as tijah:query does not work. To suit
our needs, I changed the query to the following form:
//===
let $c := collection("ep")
for $res in pf:tijah-query($c,"//[EMAIL PROTECTED]'research_projects'][about(.,
Distributed)]")
return $res
//===
But this results in the following error: "ERROR = !ERROR: interpret: unknown
variable 'collName'" That is why I incorporated the collection name in the
query, like this:
//===
for $res in pf:tijah-query(ep,"//[EMAIL PROTECTED]'research_projects'][about(.,
Distributed)]")
return $res
//===
However, this also does not work, as I get the following error: "ERROR =
!illegal reference to context node: at (1,29-1,30): ``.'' is unbound"
I have tried numerous of other variations, but neither of them work. Can
somebody please help us with an explanation about how we can do a full text
search within a certain node or point us at a more recent getting started page
(if it already exists)?
Kind regards,
Sander Bockting
