Hi, Say I have an index of "Product Types" and a different index of "Products" that belong to one of the types in the other index. Users will do their searches for attributes of types and products combined so the two distinct, but related indices must be combined into a single, flattened index so that the searches and relevancy ranking can be done appropriately. Let's call this 3rd index type+product index.
I've been asked by a customer to implement a custom update processor chain for the 3rd index that will get as input two values that define a relationship between a product and its corresponding type. In other words, the documents posted to the type+product index would simply be a value that corresponds with the uniqueId of a product type doc and another value that represents the uniqueId of the specific product of that type. An update processor would then read all fields stored in the product type index and append them to the document, then another update processor would take the other key and read the stored fields in the products index to also append them to the doc that will then be ready to be indexed into the 3rd core for merged content. I explained to the customer already that this would be custom development, for which we would need to extend various classes and implement ourselves the desired logic (not modifying anything in trunk, preferably). Has anyone implemented something similar? Is there anything that would prevent this from being possible in Solr? Here is an example scenario to illustrate what I've been asked to implement. Product Types: ***************** T1 car T2 truck T3 motorcycle Products: ********** 1 white $14500 2 red $ 5600 3 white $ 3300 4 blue $ 88000 Possible searches: ********************* white car red motorcycle white truck Notice that with the two independent data sets above it is not possible to implement this solution. Therefore the idea to create a 3rd index (core) which will take the relationships: typeId = T1, prodId = 1 typeId = T3, prodId = 2 typeId = T3, prodId = 3 typeId = T2, prodId = 4 To generate through a custom update processing chain an index consisting of: Type+Product **************** T1+1 car white $14500 T3+2 motorcycle red $ 5600 T3+3 motorcycle white $ 3300 T2+4 truck blue $ 88000 Thanks, Carlos
