I have an urgent problem, if someone could help. I have an XML file, which basically looks like this:

<TEI.2>

<TEI.2>
…
</TEI.2>

I then index the
element with standard index in the schema as follows:
<xs:element name = “pa”>
xs:annotation
xs:appinfo
tsd:elementInfo
tsd:physical
tsd:native
tsd:index
tsd:standard/
</tsd:index>
</tsd:native>
</tsd:physical>
</tsd:elementInfo>
</xs:appinfo>
</xs:annotation>
<xs:complexType mixed = “true”>
<xs:choice minOccurs = “0” maxOccurs = “unbounded”>
<xs:element ref = “abbr”></xs:element>
<xs:element ref = “address”></xs:element>
</xs:choice>
<xs:attribute name = “corresp” type = “xs:IDREFS”></xs:attribute>
<xs:attribute name = “synch” type = “xs:IDREFS”></xs:attribute>
</xs:complexType>
</xs:element>

The problem is the performance for the text retrieval query is not improved, rather degraded a bit. And in the output from adding <?explain?> to the query, I did not see any XqcUnnestStdIdxScan element. Does this mean I did not index correctly. FYI, the query I executed is as follows:

for $a in input()/TEI/TEI.2/body//p[contains(.“Omaha”)]
return $a
