Template
All suggestions will be defined as a template persisted in a mongo collection which will be parsed accordingly with the possible values of various attributes and reindexed in elastic index. For each kind of suggestion a template will be defined with placeholders for various attributes. The template formats would be in accordance with the product team. Example:
<bodyType> Cars
<bodyType> less than <price>
<color> <bodyType> less than <price>
templateId : f67a,
templateName : <bodyType> less than <price>,
filters : [
{
field : bodyType,
value : <bodyType>,
operator : in
},
{
field : price,
value : <price>,
operator : lte
}
]
}]

AutoSuggestion Ingestion: How Autosuggestion data is getting created?
Fetch Autosuggestion
requirements: product: empower search by providing susgestion for search params.
- Make
- Model
- Year
- Dealer
- Pricing
- ExtColor give topk result.
read system design of autosuggestion.
why separate ES index for auto suggestion?
suppose auto suggestion calls on 8 chars. the load on current ES will be 8x. search should be more relaible than auto suggestion search. need realtime for autosuggestion. so keeping less metadata. if autosuggestion index slows our search will not slow down as both are independent.
II. How to Make Your System More Scalable
Optimize the Data Sync Pipeline:
Incremental Updates (Delta Syncing):
Parallelize and Distribute the Sync Workload:
Efficient Transformation Logic:
Decouple with a Staging/Alias Approach for Index Updates:
. Scale the Autosuggestion Elasticsearch Index:
Optimize Index Mappings and Settings:
edge_ngram for “type-ahead” feel, or search_as_you_type datatype).
