The response contains places that match the search\ncriteria and are also located near the specified route.\n\nTo search along a route:\n\n1. Use the Routes API to calculate a route that [returns a route's encoded\n polyline](/maps/documentation/routes/traffic_on_polylines) in the response.\n\n | **Note:** You can also encode your own polyline as described in [Encoded\n | Polyline Algorithm Format](/maps/documentation/utilities/polylinealgorithm).\n2. Use the `searchAlongRouteParameters.polyline.encodedPolyline` parameter to\n pass the route's encoded polyline to Text Search (New) to bias the search\n results to the route. The response then contains places that match the\n search criteria and are also located near the specified route.\n\nThe APIs Explorer lets you make live requests so that you can get familiar with\nthe API and the API options: \n[Try it!](#try_it)\n\nBy default, Text Search (New) performs the search along the entire route from\nthe origin to the destination as defined by the polyline. In the following\nexample, the polyline defines the route from:\n\n- **Origin**: 1600 Amphitheatre Parkway, Mountain View, CA\n- **Destination**: 24 Willie Mays Plaza, San Francisco, CA\n\nThe trip's encoded polyline for this route is represented by the string: \n\n```yaml\nwblcFptchVIFOd@G@EVw@Ms@dHKR}ApNA`AF~@Hf@TjAb@bBb@~@n@p@^Rd@~@Vz@HVz@nDLt@?d@Kr@c@~@mD`G?`@aEfGkCnDuChDm`@bb@[`@{GhHeEdEciBnnBkC`DkC~DaClEuKjT_Z|l@Qb@iR~_@}EzJ_AdB_Und@kAfCaOjZkg@vcAqBzD_]rr@iBlEaBxEgArD}AlG}AhHsA`IeAnH{@dIq@dJgL~iBq@rHu@vGgAtHwArHaBhHkBzG_DpJ}Nbc@iBhGkA|EgC|LcIjb@oAhG_AvDgAdDkApC_BzCiBpCsFvGii@vn@scAxlAmLjNgSzUeRjT{TzWqExEmG|FuNlMmMhLaRvPqOlNmbAl}@mFlF{PlOmJfIoElE}LtMiSbU_H`I}}@jcAwl@vp@oAbBqA~BeAhCm@tBg@fCWrBQ~BI|DaB~rBO~D[bEa@`Dm@pDaAdE{@vC_BbEkB~Def@|z@sEzHKJeS~]}K`S{\\\\~l@cXpe@sBpDm@bAuCxDkBrBiC~BwCtByBnAcBx@}Bt@{Bn@gh@|LaOpDeFhAoDj@aE^kVrA_E^iEr@yD~@uBr@gMjF_EnAcCh@eFr@_DRsAD}@Jsu@xCWDqIV}BCeCOyDm@cBa@_DmA}JeE_CwAsBcBiBoBuAqBmOoX{CuEkB_CoDqDkVoUoD{CeE_DkEkC_FeCqB}@sDuAoDgAeCe@cCW}CK}BDaDTeOlBcuBrYaNlBq@Dyd@rGyFt@yBb@eBf@oCnAoBlAkIpGkAp@wBbAaCt@oFdAwKjBoGxA{FbByIjC_HfB_@KmNdDuC|@uFzBcH|C{@\\\\[?sBv@}@VaBVoA@y@EmAQcA[w@]aBkAeAkA}BuDUKs@uAqBsCwBcCgAiAiN_MyKsJsG{GkBaBiBuA{BwAwDkBcOaHiC_AiCg@}BQcCAcBHqBVkB`@qEjAu@LgCVgAHwG@sG?mABsH^eNr@mBXy@NqBt@uAt@aBlAkAlA}BtCyApBiAdB_BxB{A`B}@j@oAf@s@PeCVcIf@gAAkAQy@YiAo@_A{@_DgEgJqM_DeEaM}PoBiCzAsBw@kAdAGVk@f@q@z@C\n```\n| **Note:** Search along route only supports an encoded polyline, which can be passed as a string and includes compression with minimal lossiness. This is the Routes API default output. For more information, see [Request route\n| polylines](/maps/documentation/routes/traffic_on_polylines).\n\nThe following example uses the route's encoded polyline to bias the search\nresults: \n\n```scdoc\n curl -X POST -d '{\n \"textQuery\" : \"Spicy Vegetarian Food\",\n \"searchAlongRouteParameters\": {\n \"polyline\": {\n \"encodedPolyline\": \"\u003cvar translate=\"no\"\u003eROUTE_POLYLINE\u003c/var\u003e\"\n }\n }\n }' \\\n -H 'Content-Type: application/json' -H 'X-Goog-Api-Key: API_KEY' \\\n -H 'X-Goog-FieldMask: places.displayName,places.formattedAddress,places.priceLevel' \\\n 'https://places.googleapis.com/v1/places:searchText'\n```\n\nThe response contains the places that match the search criteria, biased to the\nroute: \n\n```yaml\n {\n \"places\": [\n {\n \"formattedAddress\": \"60 Morris St, San Francisco, CA 94107, USA\",\n \"priceLevel\": \"PRICE_LEVEL_MODERATE\",\n \"displayName\": {\n \"text\": \"Umami Express\",\n \"languageCode\": \"en\"\n }\n },\n {\n \"formattedAddress\": \"1130 4th St, San Francisco, CA 94158, USA\",\n \"priceLevel\": \"PRICE_LEVEL_MODERATE\",\n \"displayName\": {\n \"text\": \"House of Tadu Ethiopian Kitchen\",\n \"languageCode\": \"en\"\n }\n },\n {\n \"formattedAddress\": \"1602 El Camino Real Ste A, Belmont, CA 94002, USA\",\n \"priceLevel\": \"PRICE_LEVEL_MODERATE\",\n \"displayName\": {\n \"text\": \"Eats Meets West Bowls\",\n \"languageCode\": \"en\"\n }\n },\n /.../\n ]\n }\n```\n\nYou don't have to bias the results to the entire route. For example, you might\nalready be halfway along the route before you perform the search. In this case,\nyou can specify an explicit routing origin to the search to override the origin\ndefined in the encoded polyline. In the following example, you specify the\nlatitude and longitude coordinates of San Mateo, CA, which is approximately\nhalfway along the route polyline: \n\n```scdoc\n curl -X POST -d '{\n \"textQuery\" : \"Spicy Vegetarian Food\",\n \"searchAlongRouteParameters\": {\n \"polyline\": {\n \"encodedPolyline\": \"\u003cvar translate=\"no\"\u003eROUTE_POLYLINE\u003c/var\u003e\"\n }\n },\n \"routingParameters\": {\n \"origin\": {\n \"latitude\": 37.56617,\n \"longitude\": -122.30870\n }\n }\n }' \\\n -H 'Content-Type: application/json' -H 'X-Goog-Api-Key: API_KEY' \\\n -H 'X-Goog-FieldMask: places.displayName,places.formattedAddress,places.priceLevel' \\\n 'https://places.googleapis.com/v1/places:searchText'\n```\n| **Note:** Because search along route returns places with minimal detour times from origin to destination, in cases where the route origin and destination are the same or close to one another, search along route may not return any results.\n\nTry it!\n-------\n\nThe APIs Explorer lets you make sample requests so\nthat you can get familiar with the API and the API options.\n\n1.
