干草堆和Solr-Schema解析失败

Question

I'm trying to rebuild_index, but after building the schema ( manage.py build_solr_schema ) I copy and paste the output in the schema.xml file. After restarting the server and rebuild_index ( manage.py rebuild_index ) I'm getting the below error. I've been trying to get the problem, yet no success! What I'm I missing? Should I first delete the XML codes in the schema file before pasting the new one?

  HTTP Status 500 - Severe errors in solr configuration. Check your log files for more detailed information on what may be wrong. If you want solr to continue after configuration errors, change: <abortOnConfigurationError>false</abortOnConfigurationError> in solr.xml -------------------------------------------------------------

Answer 1

Django Haystack only supports Solr 3.5+

http://django-haystack.readthedocs.org/en/latest/backend_support.html#id1

If you're using Solr 1.4, the schema format has changed between 1.4 and 3.5

Answer 2

I don't run Solr, hence can't test this, but a few problems jump out at me (more accurately, are flagged as errors when I try to prettyprint the XML :-) )

• line 40 ( <!-- A Trie based date field ... ) ends in -> ; should be -->

• line 59 ( <filter class="solr.SynonymFilterFactory" ... ) contains ignore Case="true" ; should be ignoreCase="true" (no space in attr name)

If you fix these errors, it will most likely solve your problem.
