Hi,
let's say I store a catalogue of household appliances in Elasticsearch. Documents in my index can represent dish washers, washing machines, freezers and similar devices.
Dish washers have a text field "type" which can contain one of the following strings:
- integrated
- semi-integrated
- freestanding
- table top
If a search string contains any of these terms I want to automatically apply a filter to my query.
For example if the search string contains 'table top' I want to only select documents where type is exactly 'table top'.
Dish washer type is only one of many filters I want to apply automatically. If a user was searching for a cooker, the type could be something like 'gas cooker' or 'induction cooker'. Of course there can be more than one filter per device. A cooker could also be 'with grill' or 'without grill'. That information would be in a dedicated field 'grill' and I would like to apply a filter on that field as well if the search string contains 'with grill' or 'without grill'.
Pseudo code for what I want to achieve in Elasticsearch:
- search string = 'semi-integrated dish washer' should only return documents where type = "semi-integrated"'
- search string = 'gas cooker with grill' should only return documents where type = "gas cooker" and grill = 'with grill'
I could try to solve this outside of a Elasticsearch for example in plain Java code, but then I could not take advantage of Elasticsearch features like synonyms, so: What is the best way to achieve this in Elasticsearch?
