I’m using Solr 1.4.1. I need to boost a field. My schema.xml is the following:

I need to do the following: I need to give more importance to the “job_title” field. If for example I’m searching for the word “programmer” I need to show in the first place the results that have “programmer” in the “job_title” field ordered by date and then the results that have the word “programmer” in the “job_description” field. It is better to do an example, my english is not the best in the world 😉
I have this data:
job_title | job_description | date_inserted
programmer | job for IT guys | 10-Nov-2011
IT Python | for python programmer | 12-Nov-2011
PHP programmer | PHP programming | 08-Nov-2011
I need for example when searching for the word “programmer” to give more importance to the field “job_title” but show also in the results the documents that have the word “programmer” in the “job_description” field. I need also to give importance to the “date_inserted” field, so that the results appears like this:
job_title | job_description | date_inserted
programmer | job for IT guys | 10-Nov-2011
PHP programmer | PHP programming | 08-Nov-2011
IT Python | for python programmer | 12-Nov-2011
I’m doing a query like this:
/?facet=on&sort=date_inserted+desc&fl=*+score&start=0&q=programmer&bf=job_title:programmer^1.50&facet.field=location_ad_exact&facet.field=zone_ad_exact&fq=django_ct:(myapp.jobsadstext)&rows=20
But the result of this query is not what I need.
Can someone give me a clue about the track I need to follow to achieve the result?
