Figure out which synonyms to add and how to do it wit OR-search (expand search with more OR-queries, but boost the original query)

The general strategy would be to index stems on the way in, and then do a search for the search term and its stem.

I was more thinking about something like: car -> transportation When the user has one vocabulary, and the content/organization a different vocabulary.

Sorry- yes, you are talking about synonyms and I am talking about stemming- doh!

fergiemcdowall commented 8 years ago

In a way, synonyms are easier to solve, because you just set up a query processor that substitutes in the synonym

[
  {
    AND: {body: ['car', 'repair']}
  }
]

...transformation ('car' -> 'automobile')...

[
  {
    AND: {body: ['car', 'repair']}
  },
  {
    AND: {body: ['automobile', 'repair']}
  }
]

And, you can get some clear indications that you need to add synonyms if you have logging on 0 results queries.

Could be cool to create a small synonyms module where you could connect a google drive spreadsheet with synonyms.

Just the layout for the synonyms-module.
