/**
* Returns the answer to a query in order to highlight it via javascript.
*
* A result can contain multiple words, multiple matches, multiple pars and
* multiple boxes, for example when the answer is on two lines or pages.
*
* The resulted javascript/json is echoed and sent via Ajax.
*
* The structure of the json object is:
* ->ia = item id
* ->q = query
* ->page_count = page count (useless)
* ->body_length = body lenght (useless)
* ->leaf0_missing = generally empty
* ->matches = results as array of objects
* ->text = few words to contextualize the result, used in nav bar
* ->par = array of parallel images (currently, only the [0] is used)
* ->t = top limit of global zone
* ->l = left limit of global zone
* ->b = bottom limit of global zone
* ->r = right limit of global zone
* ->page = page number
* ->index = page index
* ->boxes = array of coordinates of boxes to highlight
* ->t = top limit of word zone
* ->l = left limit of word zone
* ->b = bottom limit of word zone
* ->r = right limit of word zone
* ->page = page number
* ->index = page index
* Note that only one of "page" or "index" is needed. Index is prefered,
* because it's generally simpler to manage and more efficient.
