Scoring strange when searching for 2x4

[PTC-JoshuaMatthews]

Using a query like

`
var results = index.query(function (q) {

        q.term(lunr.tokenizer(currentFilter), { boost: 100, usePipeline: true, fields: fields })

        q.term(lunr.tokenizer(currentFilter), { boost: 10, usePipeline: false, fields: fields, wildcard: lunr.Query.wildcard.LEADING | lunr.Query.wildcard.TRAILING })

        q.term(lunr.tokenizer(currentFilter), { boost: 5, editDistance: 1, fields: fields })

        q.term(lunr.tokenizer(currentFilter), { boost: 1, editDistance: 2, fields: fields })

      })

`

When I search for 2x4 it treats 2 and 4 as two separate tokens and ends up scoring results that contains lots of 2's and 4's higher than results that directly contain 2x4

Is there anyway to make it parse 2x4 as a single search term?
