The problem you are trying to solve is that you cannot use
${dataimporter.last_index_time} as is. you may need something like
${dataimporter.last_index_time} - 3secs
am I right?
There are no straight ways to do this .
1) you may write your own function say 'lastIndexMinus3Secs' and add
them. functions can be plugged in to DIH using a <function
name="lastIndexMinus3Secs" class=""foo.Foo/> under the <dataConfig>
tag. And you can use it as
${dataimporter.functions.lastIndexMinus3Secs()}
this will add to the existing in-built functions
http://wiki.apache.org/solr/DataImportHandler#head-5675e913396a42eb7c6c5d3c894ada5dadbb62d7
the class must extend org.apache.solr.handler.dataimport.Evaluator
we may add a standard function for this too . you can raise an issue
