With selectors, one can narrow down the list of\nretrieved entities and order it. Most selectors have the following\nmethods:\n\n`withCondition()`\n: Adds a condition to a selector. If multiple conditions are used, they are\n AND-ed together, in other words, the selector will only return entities that\n satisfy **all** of the specified conditions.\n\n`withIds()`\n: Adds a collection of [IDs](/google-ads/scripts/docs/concepts/ids) as a\n condition. An ID-based condition will be AND-ed together with all the others.\n\n`forDateRange()`\n: Is needed when a condition or ordering clause references a\n [Stats](/google-ads/scripts/docs/reference/adsapp/adsapp_stats) field, such as\n Ctr or Impressions. If you request all campaigns with over 100 impressions,\n Google Ads scripts will need to know the date range to look into.\n\n`orderBy()`\n: Specifies the ordering of the returned entities.\n\n`withLimit()`\n: Limits the number of returned entities to the specified value. It is\n particularly useful in conjunction with `orderBy()` in order to fetch things\n like \"10 keywords with most impressions yesterday\". By default, all selectors\n will set the limit to 50,000. You can increase the limit by manually specifying\n a limit.\n\nThese methods can be called in any order. One exception is `orderBy()`, where\norder of calls indeed matters: multiple calls to this method will specify\nmultiple ordering clauses, and they will apply in order. Consider the\nfollowing snippet: \n\n selector = selector.forDateRange(\"LAST_14_DAYS\")\n .orderBy(\"metrics.clicks DESC\")\n .orderBy(\"metrics.ctr ASC\");\n\nThe results will be ordered by Clicks in descending order. Results with equal\nClicks values will be ordered by Ctr in ascending order.\n\nCalls to a selector's methods can be chained together. The following code \n\n var campaignSelector = AdsApp.campaigns();\n campaignSelector.withCondition(\"metrics.clicks \u003e 10\");\n campaignSelector.withCondition(\"metrics.impressions \u003e 1000\");\n campaignSelector.orderBy(\"metrics.impressions DESC\");\n campaignSelector.forDateRange(\"YESTERDAY\");\n\ncan be re-written in a more compact fashion: \n\n var campaignSelector = AdsApp.campaigns()\n .withCondition(\"metrics.clicks \u003e 10\")\n .withCondition(\"metrics.impressions \u003e 1000\")\n .orderBy(\"metrics.impressions DESC\")\n .forDateRange(\"YESTERDAY\");\n\nOnce the selector is constructed, one can obtain an\n[Iterator](/google-ads/scripts/docs/concepts/iterators) from it by calling\n`selector.get()`.\n| **Note:** Some selectors (for example [`AdParamSelector`](/google-ads/scripts/docs/reference/adsapp/adsapp_adparamselector) and [`LabelSelector`](/google-ads/scripts/docs/reference/adsapp/adsapp_labelselector)) expose fewer methods since they operate on entities that are more restricted (don't have any stats or meaningful fields to order by).\n\nRead [Best Practices](/google-ads/scripts/docs/best-practices) for tips\nand tricks on efficient selector usage."]]
