问题 I have documents across 2 different databases: fruits, vegetables. It's easier for me to keep the databases separated. Now, suppose I want my user to search from any combination of these databases. Would it work if I run the same query across the three databases, and merge the result. That is: does the order field in a results have an absolute value, or is it relative to the other results? For example: Run my query on fruits db: { total_rows: 2, bookmark: "xxx", rows: [ { id: "Apple", order:

问题 The only reasonable slide set I found is this, which in page 15 says, for building: Sort all points by their x coordinate value and store them in the leaf nodes of a balanced binary tree (i.e., a range tree) Starting at the root, each node contains the point in its subtree with the maximum value for its y coordinate that has not been stored at a shallower depth in the tree; if no such node exists, then node is empty I implemented a Range Tree just before, so based on the example I used there,

问题 In our project, we use search engine, but the result need to be ranked based on each user's interest, similar to recommendation according to users' keyword. If we separate the two system, it would cost a lot time. Is there a better way to combine Search Engine and Recommend System together? Or is there a simple way to customize my ranking strategy to achieve this? 回答1: This is what we were trying to do in our project as well. There are two things while solving this problem - Relevancy vs

问题 Can I search for 1 AND 2 AND 3 without getting a false match because 11,22,33 are in the field? A field that has the string = "11,22,33" should then not return any results. 回答1: First of all, using comma separated values in a field is problematic, and you should consider storing them in a sepatate table instead. Then you could get the record more efficiently: select ... from mainTable t inner join valueTable v1 on v1.id = t.id and v1.value = 1 inner join valueTable v2 on v2.id = t.id and v2

问题 Good morning, all, My question today is regarding multi-field search. I have a split form (fields and individual record at the top, all data in datasheet view on the bottom). I have multiple fields I would like to search on, so that a user may find a particular person based on a number of criteria.
