Firebase Firestore复合查询变体

我有一个动态构造的Firestore查询,如下所示:

    let db = firebase.firestore().collection('vehData')

    if (this.filters.model.selected) {
      db = db.where('Model', '==', this.filters.model.selected)
    }

    if (this.filters.condition.selected) {
      db = db.where('TitleStatus', '==', this.filters.condition.selected)
    }

    if (this.filters.year.selected) {
      db = db.where('Year', '==', this.filters.year.selected)
    }

    if (this.filters.autopilot.selected) {
      db = db.where('Autopilot', '==', this.filters.autopilot.selected)
    }

    if (this.filters.battery.selected) {
      db = db.where('Battery', '==', this.filters.battery.selected)
    }

    if (this.filters.sortBy.selected) {
      db = db.orderBy(this.filters.sortBy.selected, this.filters.sortBy.ascOrDesc)
    }

    db.limit(200).get().then((querySnapshot) => { ... })

this.filters

Model ASC TitleStatus ASC 或者 Model ASC TitleStatus ASC Year ASC 或者 Model ASC TitleStatus ASC Year ASC Autopilot ASC

为每个场景/可能的过滤器组合建立索引显然不是一个选择,有人知道我如何绕过这个限制吗?
