Hi Abhishek, One of the features of search:search is that it can parse the search query. That requires string parsing, which usually gets exponentially slower with the length of the string that needs to be parsed. Also, search:search translates to something expressed in cts on the backend. So, if you know really well what needs to be done, scenario 2 is likely to be faster.
But you have to construct your query somehow, so that will take performance anyhow. If you end up doing string parsing yourself, don't bother and use search:search. It also comes with additional goodies, you probably don't want to reinvent if you need them..

My question is more inclined to the performance of parsing the query text using search:parse API OR creating the element-value-query with the values.Query profiling suggest that the process of parsing the query text using search:parse is taking more time than creating the element-value-query. Below is my testing scenario Scenario 1 Using search:parse import module namespace search = "http://marklogic.com/appservices/search"; at "/MarkLogic/appservices/search/search.xqy"; let $options := <options xmlns="http://marklogic.com/appservices/search";> <constraint name="suggest" facet="true"> <range type="xs:string"> <element name="suggest"/> </range> </constraint> </options> return search:parse('suggest:"kolkata" OR suggest:"kolkata.......to 10000 times"',$options) (: Taking more time to parse the query :) Scenario 2 cts:element-value-query(xs:QName("suggest"),("kolkata", "kolkata".......to 10000 times)) (: More efficient :) Let me know your idea !

I would guess that using search:parse would be more efficient, but more importantly, it will get you the query you want. Otherwise you will have to reimplement it to parse the constraints. Is it taking a long time? Have you tried profiling it to see where it is spending time? -Danny From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Abhishek53 S Sent: Monday, June 27, 2011 11:05 AM To: General MarkLogic Developer Discussion Cc: [email protected]<mailto:[email protected]> Subject: [MarkLogic Dev General] Query Parsing Hi Folks (1) Currently my search application input is query text. eg "constr1:value1 OR constr2:value2".This requires to be parsed separately using search:parse API. The output query xml is converted to cts:query and then passed to the additional query (required to be excluded for highlighting). The query text can be very large and complex. (2) In spite of sending the query text if the application send the constraint values then the cts:query can be created and directly send to the additional query. This can save the additional step of parsing the query. e.g. additional-query = cts:or-query(($some-xml//values)) My area of concern is which would be more efficient term of performance 1. Creating cts query (2) from the values sent from application 2. Parsing the query using search:parse (1) and then casting to cts:query Thanks in advance !
