Wondering if there is a way to determine if search terms are nouns. Could some sort of dictionary list be put together and stored, then gives some weight to items in this list? Anyone ever done anything such as this? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

This process is easier (but still not easy) if you pre-process your data on the client side at indexing time. You can mark your terms with their respective Parts of Speech using a payload filter: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

You can then access the payload via scripts and calculate a score accordingly: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

Using payloads is more common in Lucene, but I have never seen anyone do it in Elasticsearch. -- Ivan On Wed, Aug 27, 2014 at 1:10 PM, Eric Greene [ericdgreene@gmail.com](mailto:ericdgreene@gmail.com) wrote: > Wondering if there is a way to determine if search terms are nouns. > > Could some sort of dictionary list be put together and stored, then gives > some weight to items in this list? > > Anyone ever done anything such as this? > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > To view this discussion on the web visit > [https://groups.google.com/d/msgid/elasticsearch/77141403-c119-49c2-9952-ca98e60252b0%40googlegroups.com](https://groups.google.com/d/msgid/elasticsearch/77141403-c119-49c2-9952-ca98e60252b0%40googlegroups.com) > [https://groups.google.com/d/msgid/elasticsearch/77141403-c119-49c2-9952-ca98e60252b0%40googlegroups.com?utm\_medium=email&utm\_source=footer](https://groups.google.com/d/msgid/elasticsearch/77141403-c119-49c2-9952-ca98e60252b0%40googlegroups.com?utm_medium=email&utm_source=footer) > . > For more options, visit [https://groups.google.com/d/optout](https://groups.google.com/d/optout). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Contribute to jprante/elasticsearch-analysis-baseform development by creating an account on GitHub. I also provide an english noun file [https://github.com/jprante/elasticsearch-analysis-baseform/blob/master/src/main/resources/baseform/en-nouns-lemma-utf8.txt?raw=true](https://github.com/jprante/elasticsearch-analysis-baseform/blob/master/src/main/resources/baseform/en-nouns-lemma-utf8.txt?raw=true) so with a bit of modification of the FST in the analysis, you could create a tagger for english nouns (or more precisely, for the words in the given file). Then, like Ivan said, with the delimited token filter and function score, it would be possible to implement english noun boosting.
