I am trying to search on a solr core which contains static data without any Sitecore details.

<str name="_property_text">1</str>
<str name="_itemnumber_string">1250000</str>
<str name="_propertykey_string">Black</str>

When I try to make a search using the content search manager it will always return an empty result.

var index= ContentSearchManager.GetIndex("index_name");
 using (var ctx = comboIndex.CreateSearchContext()){
     var queryable = ctx.GetQueryable<CustomSearchModel>();

    Why are you trying to use the Sitecore Search API on a non-Sitecore index? Just use Solr.net.

The field you're missing is going to be _indexname. It will need to be set to the name of the index you are searching, in your case index_name. If you look at the Search.log in the data folder, you will see exactly what query string Sitecore is generating. At the end, you should see that it is generating fq=_indexname:index_name. You can test this by adding the _indexname field to all of your documents and checking if they then get returned.

I believe that this is the only field that Sitecore requires, but there may be others.
