 * @param {*} searchTerm The term to be searched for
 * @param {*} resultLimit The limit of results that can be obtained
 * @param {*} page decides the amount of skips to emulate pagination, following (page-1)*resultLimit
 * @returns a fully constructed search query suitable for the aggregate function. Currfently only works with the "GETSearchOptimized" Index
