     17It seems that not often, XPATH queries are used on a Lucene index. We do not have all ebRIM data in memory, therefore we cannot simply evaluate XPATH queries against complete ebRIM documents. This suggests that the best option is to evaluate XPATH queries against the Lucene index. How should we go about doing that ?
