Question content

I am trying to perform a search on the elasticsearch client in go (olivere/elastic) using the corresponding client library for elasticsearch version 7.x. The expected behavior is that the code compiles without errors and returns scrollable search results with the specified query, aggregation, size, track total hits, pretty, and sorting options.

However, the actual behavior generates an error message stating that the aggregation, size, tracktotalhits, pretty, sort and do methods are not recognized. This error message may indicate a problem with the syntax or references of elasticsearch client methods.

Can anyone suggest steps to resolve this issue and help me resolve the error? Also, please find below the code I'm currently using:

searchResult, err := r.elasticClient.
    Scroll().
    Index(r.index).
    Query(query).
    Aggregation("agg", agg).
    Size(limit).
    TrackTotalHits(true).
    Pretty(true).
    Sort("startTime", true).
    Do(context.Background())

thanks for your help!
