【问题描述】：
我目前正在使用 PHP 从我的 sphinx 索引中查询。索引正在正确构建，但搜索却没有。
最初我的查询设置如下：
private function _doMapSearchAll($textSearch, $typeFilterArr, $rads = array(), $centre = array(), $showFavourites = false) {
// lookup the location based on the search and return the results in that
// map bounds ignore for boundary searches
$rsArr = array();
$skipDataSearch = false;
if (!COUNT($rads)) {
// handle airport code lookups if we have 3 characters
if (strlen($textSearch) === 3) {
$rsArr = $this->_doMapAirportSearch($textSearch);
if (COUNT($rsArr)) {
$skipDataSearch = true;
}
}
// still no results based on the above search, do generic map search
if ($skipDataSearch === false) {
$rsArr = $this->_doMapGeoSearch($textSearch, $typeFilterArr, $centre);
if (COUNT($rsArr['results']) > 0) {
$skipDataSearch = false;
}
}
}
// if we are doing a boundary search, or we have no results from the above,
// get all results based on our location
if ($skipDataSearch === false) {
// fall back onto searching via the data
// normalise the search string
$originalSearchString = $this->doNormalisation($textSearch);
// use sphinx for the search
$sphinx = $this->_getSphinxConnection();
$sphinx->setLimits(0, $this->container->getParameter('search_max_results'), $this->container->getParameter('search_max_results'));
if (COUNT($typeFilterArr)) {
$sphinx->SetFilter('fldSiteTypeUID_attr', $typeFilterArr);
}
// if we're doing a boundary search, skip the search string
if (COUNT($rads) > 0) {
$originalSearchString = '';
if ($showFavourites === false) {
//$sphinx->SetFilterFloatRange('lat_radians', min($rads['minLat'], $rads['maxLat']), max($rads['minLat'], $rads['maxLat']));
//$sphinx->SetFilterFloatRange('long_radians', min($rads['minLon'], $rads['maxLon']), max($rads['minLon'], $rads['maxLon']));
if ($rads['minLat'] > $rads['maxLat']) {
$rads['minLat'] = $rads['minLat'] - 360;
}
if ($rads['minLon'] > $rads['maxLon']) {
$rads['minLon'] = $rads['minLon'] - 180;
}
$sphinx->SetFilterFloatRange('lat_radians', $rads['minLat'], $rads['maxLat']);
$sphinx->SetFilterFloatRange('long_radians', $rads['minLon'], $rads['maxLon']);
}
}
// order by centre point
if (COUNT($centre) > 0) {
// otherwise start in the centre
$sphinx->SetGeoAnchor('lat_radians', 'long_radians', (float) $centre['centreLat'], (float) $centre['centreLon']);
$lintDistanceLimit = 999999999.0; // everything
if ($showFavourites === false && isset($rads['maxLat'])) {
$radiusMiles = $this->get('geolocation_helper')->getSeparation(
rad2deg($rads['maxLat']),
rad2deg($rads['minLon']),
rad2deg($rads['minLat']),
rad2deg($rads['maxLon']),
"M"
);
$lintDistanceLimit = $radiusMiles * 1609; // miles to meters...
}
$sphinx->SetFilterFloatRange('geodist', 0.0, (float)$lintDistanceLimit);
$sphinx->SetSortMode(SPH_SORT_EXTENDED, 'geodist ASC');
} else {
// apply search weights
$sphinx->SetFieldWeights(array('fldTown_str' => 100, 'fldAddress1_str' => 30, 'fldSiteName_str' => 20));
}
// if we should be limiting to only favourites, pickup the selected
// favourites from cookies
if ($showFavourites === true) {
$request = $this->container->get('request_stack')->getCurrentRequest();
$favourites = explode(',', $request->cookies->get('HSF_favlist'));
if (count($favourites)) {
foreach ($favourites as $k => $favourite) {
$favourites[$k] = (int)$favourite;
}
$sphinx->SetFilter('fldUID_attr', $favourites);
}
}
$rs = $sphinx->Query($originalSearchString, $this->container->getParameter('sphinx_index'));
echo json_encode($sphinx);
$rsArr['results'] = array();
if (isset($rs['matches']) && count($rs['matches'])) {
// update the search text to what we actually searched for, this
// is needed in case we've updated/set $rsArr['searchText']
// after a geolookup
$rsArr['searchText'] = $textSearch;
// clear any previous bounds set by the geolookup, we don't want this
// if we have direct text match results
$rsArr['geobounds'] = array();
if (isset($rs['matches']) && count($rs['matches'])) {
foreach ($rs['matches'] as $k => $match) {
$rsArr['results'][$k] = $this->_remapSphinxData($k, $match);
}
}
// sort the results by distance
usort($rsArr['results'], function ($a, $b) {
return $a['fldDistance'] - $b['fldDistance'];
});
}
}
// add on the total record count
$rsArr['total'] = (int) COUNT($rsArr['results']);
return $rsArr;
}
这没有返回任何东西，并给了我 GEODIST() 的错误：
{"_host":"sphinx","_port":36307,"_path":"","_socket":false,"_offset":0,"_limit":250,"_mode":0,"_weights":[],"_sort":4,"_sortby":"geodist ASC","_min_id":0,"_max_id":0,"_filters":[{"type":2,"attr":"geodist","exclude":false,"min":0,"max":999999999}],"_groupby":"","_groupfunc":0,"_groupsort":"@group desc","_groupdistinct":"","_maxmatches":"250","_cutoff":0,"_retrycount":0,"_retrydelay":0,"_anchor":{"attrlat":"lat_radians","attrlong":"long_radians","lat":0.9300859583877783,"long":-2.0943951023931953},"_indexweights":[],"_ranker":0,"_rankexpr":"","_maxquerytime":0,"_fieldweights":[],"_overrides":[],"_select":"*","_error":"searchd error: geoanchor is deprecated (and slow); use GEODIST() expression","_warning":"","_connerror":false,"_reqs":[],"_mbenc":"","_arrayresult":false,"_timeout":0}{"results":[],"bounds":{"bllat":53.395603,"trlat":53.7159857,"bllng":-113.7138017,"trlng":-113.2716433},"geocentre":{"lat":53.5461245,"lon":-113.4938229},"checksum":"204a43923452936b00a10c8e566c4a48d4fdb280f97fd4042646eb45c8257bbc","searchText":"Edmonton, AB, Canada","skipResults":true,"showFavourites":false}
为了解决这个问题，我将 SetGeoAnchor 函数更改为以下内容：
private function _doMapSearchAll($textSearch, $typeFilterArr, $rads = array(), $centre = array(), $showFavourites = false) {
// lookup the location based on the search and return the results in that
// map bounds ignore for boundary searches

$skipDataSearch = false;
if (!COUNT($rads)) {
// handle airport code lookups if we have 3 characters
if (strlen($textSearch) === 3) {
$rsArr = $this->_doMapAirportSearch($textSearch);
if (COUNT($rsArr)) {
$skipDataSearch = true;
}
}
// still no results based on the above search, do generic map search
if ($skipDataSearch === false) {
$rsArr = $this->_doMapGeoSearch($textSearch, $typeFilterArr, $centre);
if (COUNT($rsArr['results']) > 0) {
$skipDataSearch = false;
}
}
}
// if we are doing a boundary search, or we have no results from the above,
// get all results based on our location
if ($skipDataSearch === false) {
// fall back onto searching via the data
// normalise the search string
$originalSearchString = $this->doNormalisation($textSearch);
// use sphinx for the search
$sphinx = $this->_getSphinxConnection();
$sphinx->setLimits(0, $this->container->getParameter('search_max_results'), $this->container->getParameter('search_max_results'));
if (COUNT($typeFilterArr)) {
$sphinx->SetFilter('fldSiteTypeUID_attr', $typeFilterArr);
}
// if we're doing a boundary search, skip the search string
if (COUNT($rads) > 0) {
$originalSearchString = '';
if ($showFavourites === false) {
//$sphinx->SetFilterFloatRange('lat_radians', min($rads['minLat'], $rads['maxLat']), max($rads['minLat'], $rads['maxLat']));
//$sphinx->SetFilterFloatRange('long_radians', min($rads['minLon'], $rads['maxLon']), max($rads['minLon'], $rads['maxLon']));
if ($rads['minLat'] > $rads['maxLat']) {
$rads['minLat'] = $rads['minLat'] - 360;
}
if ($rads['minLon'] > $rads['maxLon']) {
$rads['minLon'] = $rads['minLon'] - 180;
}
$sphinx->SetFilterFloatRange('lat_radians', $rads['minLat'], $rads['maxLat']);
$sphinx->SetFilterFloatRange('long_radians', $rads['minLon'], $rads['maxLon']);
}
}
// order by centre point
if (COUNT($centre) > 0) {
// otherwise start in the centre
// $sphinx->SetGeoAnchor('lat_radians', 'long_radians', (float) $centre['centreLat'], (float) $centre['centreLon']);
$centreLat = (float) $centre['centreLat'];
$centreLon = (float) $centre['centreLon'];
$sphinx->SetSelect("GEODIST(lat_radians, long_radians, $centreLat, $centreLon) AS geodist");
$lintDistanceLimit = 999999999.0; // everything
if ($showFavourites === false && isset($rads['maxLat'])) {
$radiusMiles = $this->get('geolocation_helper')->getSeparation(
rad2deg($rads['maxLat']),
rad2deg($rads['minLon']),
rad2deg($rads['minLat']),
rad2deg($rads['maxLon']),
"M"
);
$lintDistanceLimit = $radiusMiles * 1609; // miles to meters...
}
$sphinx->SetFilterFloatRange('geodist', 0.0, (float)$lintDistanceLimit);
$sphinx->SetSortMode(SPH_SORT_EXTENDED, 'geodist ASC');
} else {
// apply search weights
$sphinx->SetFieldWeights(array('fldTown_str' => 100, 'fldAddress1_str' => 30, 'fldSiteName_str' => 20));
}

}
$sphinx->SetFilter('fldUID_attr', $favourites);
}
}
$rs = $sphinx->Query($originalSearchString, $this->container->getParameter('sphinx_index'));
echo json_encode($sphinx);
$rsArr['results'] = array();
if (isset($rs['matches']) && count($rs['matches'])) {

// sort the results by distance
usort($rsArr['results'], function ($a, $b) {
return $a['fldDistance'] - $b['fldDistance'];
});
}
}
// add on the total record count
$rsArr['total'] = (int) COUNT($rsArr['results']);
return $rsArr;
}
这会给我返回结果，但是它们看起来像这样：

我的搜索配置如下所示：
searchd
{
listen = 36307
listen = 9306:mysql41
log = /opt/sphinx/searchd.log
query_log = /opt/sphinx/query.log
read_timeout = 5
max_children = 30
pid_file = /opt/sphinx/searchd.pid
seamless_rotate = 1
preopen_indexes = 1
unlink_old = 1
binlog_path = /opt/sphinx/
}
我是新的 tp Sphinx，需要帮助更正此查询。有什么想法吗？
编辑：这是 sphinx 版本 3.4.1
