Hello - it looks like you have synonyms enabled at query time, which is fine, but also means TF*IDF stats are different for tbrush and toothbrush, causing this order to be the way it is. There is no solution available in Solr right now that would boost user-entered terms over expanded synonyms but you can try this [1] plugin. You can solve the second problem by using phrase boosting in dismax, see the pf parameter.
