Hi list, I've got an attribute that could contains very long strings (more than 150 chr). It's a string made of small tokens separated by spaces and slashes : departmentUID: BA/BAC ANDL/BAPZ IDF/GRPT YVLN/CIE GN ST GERM... The attibute is indexed with pres,eq,sub When I search for small substrings like (departmentUID=*/GRPT*) it's fast and ok. When I search for a long subset of the string, the query is very long (many seconds) : (departmentUID=BA/BAC ANDL/BAPZ IDF/GRPT YVLN/CIE GN ST*) The more the string is long, the more the answer is slow. I can use very complex filters (&((|()())(|()()))... and the answer is very fast, unless I use a long string in it. The backend is BDB (berkeley 4.2) Openldap is 2.2.26 Is this a BDB or an Openldap related issue ? Using subinitial or subany in the index slap.conf parameter did not solve the problem. I found only one post in the archives related to a server were any query string with more than 3 characters makes slow answers. He was told to adjust : index_substr_if_minlen index_substr_if_maxlen index_substr_any_len index_substr_any_stepBut theses parameters are only available with openldap 2.3 and it doesn't seem to be exactly my problem (I've no differences between 2,3,4 or 5 characters query strings) Thanks, Sylvain. |
