Hi Adi,
How does your new code look like? How did you rewrite the collection function?

Hi Martin, I am working with collection data base only from starting on wards.
Through
mail it is not possible to share the large collection db(more than 7GB) thats why I am sharing sample query(with xml doc but actually I am using collection only). I have tried all your suggestions in the trail mail ,but it takes more
time
in 8.2.3 than 7.9 version. Can you please guide me to proceed further.
Thanks & Regards, Adi

HI Adi, Have you tried Max's suggestion of adding the xml data to a BaseX
db
first? Based on this:
for $details in
(collection("E:\Web-Projects\VodafoneUK\Docs\Cloud_Test_Stats\Performance_Analysis\Freq_Called_Sample_XML_Data.xml")
it looks like you're using the file Freq_Called_Sample_XML_Data.xml directly from the filesystem, which means it has no indexes and must be fully scanned to get results. You should create a DB and upload that xml file with TEXTINDEX and ATTRINDEX enabled (which is the default). You
might
need to run the OPTIMIZE ALL command after uploading the xml file, you
can
run the INFO DB command and it will show if your database has up-to-date indexes or not. Once you have a db, you can also use the GUI to check
the
query plan that's being used for a particular query.

Dear Max, Currently I am using collection only(size 7.96 GB), I am sharing the
query
for your reference only. I tried the latest version 8.2.3 also but it
takes
more time than 7.9. Can you please assist me to proceed further.

Hi Adi,
some general pointers:
- Server version 7.9 is missing all the latest perf improvements,
current version is 8.2.3
- You are accessing the files in the file system - try adding them to
the database first, then you can make use of the text index etc. See http://docs.basex.org/wiki/Indexes#Text_Index
