Re: [MarkLogic Dev General] SearchAPI using search:search()

Sini -

Your first call to search:search will return at most 10 results (I think), the default. Therefore $no-of-pages will always be one (unless it returns 0 results). Then the second call to search:search asks for 1000 results, which is a very high number. This is likely your problem. Do you need that many results?

It looks like you're using search API to gather URIs. cts:uris would be a better tool for that job.

Subject: [MarkLogic Dev General] SearchAPI using search:search()

Hi All,

I'm creating a searchAPI that would perform search on a specific DB and sends back the xml response.

I have done this using search:search(). The code is working fine.

But when ever I perform a query for huge number of docs[say 90000 docs], it takes more than 10mnts to return the xml response.

Here is the code,

import module namespace search = "http://marklogic.com/appservices/search" at "/MarkLogic/appservices/search/search.xqy";

let $searchTerm := "provider:collOne AND country:USA"

let $options := <options xmlns="http://marklogic.com/appservices/search">

<return-facets>false</return-facets>

<extract-metadata><qname elem-ns="" elem-name="name"/><constraint-value ref="country"/><constraint-value ref="provider"/></extract-metadata>

</options>

let $result := search:search($searchTerm,$options)

let $totalItems := data($result//@total)

let $pageSize := xs:integer(1000)

let $no-of-pages := xs:integer(math:ceil($totalItems div $pageSize))

let $index := xs:integer(1)

return

<results>{

for $i in (1 to $no-of-pages)

let $searchResults := search:search($searchTerm, $options ,$pageSize*($i - 1)+1, $pageSize)

for $current in $searchResults//search:result

let $URI := $current/@uri/string()

return

}</results>

When I simply return the $result, it is very fast and the time it shows is <search:total-time>PT0.04323S</search:total-time> for 90000 docs.

But in the return, when I loop through the pages($no-of-pages), it takes a lot of time.

Please let me know if I'm performing something incorrect here.

Thanks,

Sini
