Hi Erik, Thanks for the links, but the analyzers are called correctly. The problem is that I need to get access to the whole set of terms through a searcher, but the request searcher cannot retrieve any terms because the commit method has not been called already.
My idea behind this is avoid two calls: first, the importer and after the updater. As there is an update processor chain than can be used after the DIH, I thorough it was possible to get a real-time updater. My specific problem is: given a set of texts, I need to make a solr index and add to this index a graph containing certain dependences between the indexed terms. So, my idea was to use an import (associating the appropriate analyzer to the textual field) and use the updateProcessorchain that: first, construct the graph, and then, add a field to link a document with a graph node. However, this does not seem to be a good approach (see Alexander reply), and I am trying to call sequentially the importer and updater. Any other proposal for avoid the double call are welcome! I am also having trouble on calling the updateProcessor to make all changes on the imported documents.
