Thanks, We will undo changes to in-memory tree size and in-memory range index. Also, will migrate as soon as posible. Do you recomended MarkLogic 5 (just released) or 4?

Higher limits mean larger in-memory stands, which will increase memory utilization. That is not likely to improve performance, and may well hurt performance. I would undo those changes. * The increased database size and memory utilization probably indicate a large number of deleted fragments, which should be visible on the database status page. Merge the database to get rid of those. 3.2 is indeed very old now, and I would recommend upgrading as quickly as is practical. Note that upgrading will require more reindexing. So I would defer the full merge, recommended above, until after that upgrade is complete. -- Mike On 13 Nov 2011, at 12:32 , Eric Bloch wrote: > I believe a formal end-of-life notice has been given for MarkLogic 3.2. > > -Eric > > Eric Bloch > [email protected] > > > > On Nov 13, 2011, at 11:11 AM, Mariano Grau Calín wrote: > >> Hi all: >> >> We had to reindexing/refragmenting the database because searchs by trailing >> date not working. >> The new documents was not indexed by date.
