That's why I asked Solr to give me documents which contain the word "solr" in a field named text. In response, I got one document which matched the given query. To simplify the example, I removed the response header part. As you can see in the response, there were a few fields that were indexed dynamically, and their names start with attr_. Those fields contained information about the file, such as the size, the application that created it, and so on. xml file, and that Apache Tika could parse and return to Solr.

37 Indexing your Data There's more... There are a few things worth mentioning. Splitting encapsulated data There are certain situations where the data is seen without the header. To inform Solr of how to parse such data, we need to pass another parameter split, either as a request parameter or a request handler configuration option. If you set the split parameter to true, Solr will split the data even if it's encapsulated. For example, if we had a field named title, which was multivalued, we could set this parameter to split the data like this: id;isbn;title 1;ABCD;"Solr Cookbook;Another title" This would result in a document with id=1, isbn=ABCD, and two titles, the first one being "Solr Cookbook" and the second one being "Another title".
