问题 Background I'm using NoSql database supporting graphs for the first time. It is a huge medical application handling thousands of patients.

问题 I have read about cts:search() and search:search() separately but could not figure out the exact difference between them. It says cts:search() ultimately uses search:search() . Can anyone illustrate in detail the scenario where one should go for cts:search() and for search:search() .This is not in relation to some particular project work where I need to implement this but in general. Thanks! 回答1: Also worth mentioning are the: Client REST API, which basically exposes the Search API as an HTTP

问题 Hi I am new to Marklogic and Apache. I have been provided task to use apache as loadbalancer for our Marklogic cluster of 3 machines. Marklogic cluster is currently running on Linux servers.

问题 I have a 50,000,000 document database that I'd like to write to a file the base-uri's for each document. Running the entire 50,000,000 is too long running (query times out). So, I thought I'd use predicates to break the database into more manageable batches. So, I tried the following to get a handle on its performance: for $i in ( 49999000 to 50000000 ) return fn:base-uri( /mainDoc[position()=$i] ) But, performance was very slow for these 1000 base uris. In fact, the query timed out. I tried

问题 We are currently using scheduled backups to have daily database backups. We are observing many problems in taking backups from past few days.

I have a query building interface that allows users to enter strings into textboxes that correspond to particular JSON properties of the documents in the db. The idea was that the user could enter the search terms exactly as the cts.parse (I use server side javascript, not XQuery) expects them, so that their searches could be arbitrarily complex and I would not have to deal with parsing the queries myself. However after doing
