Hi there,

Below is my XML Structure –

<Docs>

            <Doc>

                        <DocTitle C=”1”></DocTitle>

                        <MainDesc></MainDesc>

                        <FullDesc></FullDesc>

            </Doc>

            <Doc>

                        <DocTitle C=”2”></DocTitle>

                        <MainDesc></MainDesc>

                        <FullDesc></FullDesc>

            </Doc>

………………….

………………….

………………….

</Docs>

There are at least 6000 Doc (more to be added soon). I have created a FT Index of the same.

To search a particular word, which might be either in <MainDesc> or in <FullDesc>,

below are my queries –

Query No -1 (Time taken is 21-22 Secs)

               data(doc('sample')/Docs/Doc[MainDesc[. contains text
{'unfavorable'}] or FullDesc[. contains text {'unfavorable'}]]/DocTitle/@C)

Query No -2 (Time taken is 25-26 Secs)

               for $x in doc('sample')/Docs/Doc

where $x[MainDesc[. contains text {'unfavorable'}] or FullDesc[. contains text {'unfavorable'}]]

return $x/DocTitle/@C

The time taken is too much. How can I lower this…?

I tried ft:search(), but it doesn’t fits in here as ft:search wont return Nodes.

Have a nice day
