Instance Method Details

#add(documents, add_attrs = {}) ⇒ Object

generates "add" xml for updating solr "data" can be a hash or an array of hashes.

  • each hash should be a simple key=>value pair representing a solr doc. If a value is an array, multiple fields will be created.

"add_attrs" can be a hash for setting the add xml element attributes.

This method can also accept a block. The value yielded to the block is a Message::Document; for each solr doc in "data". You can set xml element attributes for each "doc" element or individual "field" elements.

For example:

solr.add(:nickname=>'Tim', :commitWithin=>1.0) do |doc_msg| doc_msg.attrs = 10.00 # boost the document nickname = doc_msg.field_by_name(:nickname) nickname.attrs = 20 if nickname.value=='Tim' # boost a field end

would result in an add element having the attributes boost="10.0" and a commitWithin="1.0". Each doc element would have a boost="10.0". The "nickname" field would have a boost="20.0" if the doc had a "nickname" field with the value of "Tim".
