我们在django 1.10中搜索,我们需要用trigram搜索进行用户排名搜索.
我们的代码是这样的:
def get_queryset(self):
search = self.request.GET.get('text', '')
vector = SearchVector('name',weight='A',
config=settings.SEARCH_LANGS[
settings.LANGUAGE
],
) + SearchVector(
'content',
weight='B',
config=settings.SEARCH_LANGS[
settings.LANGUAGE
],
)
query = SearchQuery(search)
return Article.objects.annotate(
rank=SearchRank(
vector,
query
),
similarity=TrigramSimilarity(
'name', search
) + TrigramSimilarity(
'content', search
),
).filter(
rank__gte=0.3
).filter(
similarity__gt=0.3
).order_by(
'-similarity'
)[:20]
但是这段代码不会返回任何查询,如果没有使用trigram,我们就会遇到问题,但是,在它们之间我们无法得到查询.
我们如何在django 1.10中组合trigram和排名搜索？
我正在制作自己的开发工具OpenEdx.
我devstack从edx中取出了官方存储库,我正在修改它.
我正在尝试添加forums到我的堆栈但我无法运行,因为docker compose.
我把它添加到composer文件中:
forums:
command: bash -c 'source /edx/app/forum/cs_comments_service_env && ruby app.rb -p 18080'
container_name: edx.devstack.forums
depends_on:
# - xqueue:xqueue
- mongo
- elasticsearch
# - rabbitmq:rabbitmq
- mysql
- memcached
environment:
CACHE_LOCATION: edx.devstack.memcached:12211
DB_HOST: edx.devstack.mysql
TEST_ELASTICSEARCH_URL: "http://edx.devstack.elasticsearch:9200"
image: edxops/forums:latest
ports:
- 4567:4567
我对运行中正确的命令感到困惑:
studio:
command: bash -c 'source /edx/app/edxapp/edxapp_env && python /edx/app/edxapp/edx-platform/manage.py cms runserver 0.0.0.0:18010 --settings devstack_docker'
这是工作室的命令.

在终端中执行此操作的步骤列表如下:
1.创建具有渗透的地图.
curl -XPUT 'localhost:9200/my-index?pretty' -H 'Content-Type: application/json' -d'
{
"mappings": {
"_doc": {
"properties": {
"title": {
"type": "text"
},
"query": {
"type": "percolator"
}
}
}
}
}
'
索引新文章:
Run Code Online (Sandbox Code Playgroud)curl -XPUT 'localhost:9200/my-index/_doc/1?refresh&pretty' -H 'Content-Type: application/json' -d' { "CourseId":35, "UnitId":12390, "id":"16069", "CourseName":"ARK102U_ARKEOLOJ?K ALAN YÖNET?M?", "FieldId":8, "field":"TAR?H", "query": { "span_near" : { "clauses" : [ { "span_term" : { "title" : "dünya" } }, { "span_term" : { "title" : "miras?" } }, { "span_term" : …
我们正在 ElasticSearch 中使用过滤器，我们需要通过短语而不是逐字获得完整的突出显示：
例如，我们有下一个搜索：
curl -X GET "localhost:9200/my-index/_search" -H 'Content-Type: application/json' -d'
{
"query" : {
"percolate" : {
"field": "query",
"document" : {
"title" : "A new bonsai tree in the office and jungle. The enojen tree in a kerojen."
}
}
},
"highlight": {
"fields": {
"title": {}
}
}
}
'
我们得到下一个输出：

所以,我有这个代码:

当我们尝试在查询不起作用unaccent后添加单词时search.我们怎样才能让django全文搜索与postgress unaccent一起工作？
