Title: DATASOLR-139 - Combination of OR | AND are not fully captured within SolrQueryCreator. 

The problem was the criterias that were already on criteriaChain were not being added when creating an OrCriteria using another Criteria. The proposed solution adds existent criteria-chain's criterias to OrCriteria when invoking org.springframework.data.solr.core.query.Criteria.or(Criteria).
