UI bug when searching: phantom search terms

[jabrah]

I navigate to the Frontinus and launch an advanced search for 'war' in marginalia + 'Caesar' in people. That works fine. I then add another search term, namely a Mars symbol. Since this search doesn't yield any results, I delete this search term in order to run the earlier search again ( 'war' in marginalia + 'Caesar' in people). However, every time I now press the search button, the third (and deleted) search term (the Mars symbol) is automatically added. Luckily this term isn't included in the search, but it's appearance is rather confusing.
