If you want want to get Farcaster user with fid in certain range, e.g. fid 1 to 3, then you can use the fid as an array to the userId input to fetch the data as shown below:

Try Demo

Code

query MyQuery {
  Socials(
    input: {
      filter: { dappName: { _eq: farcaster }, userId: { _in: ["1", "2", "3"] } }
      blockchain: ethereum
    }
  ) {
    Social {
      id
      chainId
      blockchain
      dappName
      dappSlug
      dappVersion
      userId
      userAddress
      userCreatedAtBlockTimestamp
      userCreatedAtBlockNumber
      userLastUpdatedAtBlockTimestamp
      userLastUpdatedAtBlockNumber
      userHomeURL
      userRecoveryAddress
      userAssociatedAddresses
      profileBio
      profileDisplayName
      profileImage
      profileUrl
      profileName
      profileTokenId
      profileTokenAddress
      profileCreatedAtBlockTimestamp
      profileCreatedAtBlockNumber
      profileLastUpdatedAtBlockTimestamp
      profileLastUpdatedAtBlockNumber
      profileTokenUri
      isDefault
      identity
      fnames
      isFarcasterPowerUser
    }
  }
