Search publications - https://github.com/lens-protocol/api-examples/blob/master/src/search/search-publications.ts

This query allows you to search across hashtags on publications or profile handles. This query returns either a Post and Comment or Profile.

Querying the protocol publications for content and profiles is fundamental for social visibility and something we will continue to improve on.

API details

You can search against profile handles or search against hashtags. Both will be explained in detail below.

Hot tip
If you do not know GraphQL that well remember things can be nullable if defined as so in the schema how GraphQL knows its nullable is without the ! at the end here is an example:
Not nullable:
ownedBy: EthereumAddress!
Nullable:
ownedBy: EthereumAddress
It's always worth generating the TypeScript types for the schema if your application is TypeScript here is a reference to how you would do that - https://www.apollographql.com/blog/tooling/apollo-codegen/typescript-graphql-code-generator-generate-graphql-types/

You will see the paging result behavior repeated a lot in the API. This is to allow you to fetch a certain amount and then page it for the most optimal request speed. Every time something is wrapped in a paging result, you will always get returned a pageInfo which holds the cursors for the previous and next alongside the total count which exists in the database. These cursors are just pointers for the server to get to the next result and do not need to be understood by your client or server. If you ever want to then page to the next result you can pass these previous and next cursor in the request cursor property.

Search across profiles

You can use the type property on the request which allows you to search on the same endpoint to define the type of search you want.

query Search {
  search(request: {
    query: "josh",
    type: PROFILE,
    limit: 10
  }) {
    ... on ProfileSearchResult {
      __typename 
      items {
        ... on Profile {
          ...ProfileFields
        }
      }
      pageInfo {
        prev
        totalCount
        next
      }
    }
  }

Search across publications

For now, the search will search across anything which has hashtags and tags, this will be expanded to a full-text search soon. So if someone posted #foo that can be searched but if someone posted "I like #foo" only "foo" would be searchable and not "like". A full-text search API is under active development and will be released at a later point.

query Search {
  search(request: {
    query: "hello",
    type: PUBLICATION,
    limit: 10
  }) {
    ... on PublicationSearchResult {
