Question

我正在使用java 1.7.0_95，Django 1.8.4，Python 3.4.0，Django Rest Framework 3.1.3，ElasticSearch 2.3.1，pyelasticsearch 1.4和Django Haystack 2.4.1

每次尝试python manage.py rebuild_index时，我都会遇到弹性搜索中的错误。这是错误：

MapperParsingException[Root mapping definition has unsupported parameters:  [_boost : {null_value=1.0, name=boost}]]
        at org.elasticsearch.index.mapper.DocumentMapperParser.checkNoRemainingFields(DocumentMapperParser.java:171)

        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
        at java.lang.Thread.run(Thread.java:745)

这是我的配置：

HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
        'URL': 'http://127.0.0.1:9200/',
        'INDEX_NAME': 'haystack',
    },
}

HAYSTACK_SIGNAL_PROCESSOR = 'haystack.signals.RealtimeSignalProcessor'

HAYSTACK_SEARCH_RESULTS_PER_PAGE = 40

有一个相关的django-haystack问题需要删除boost＆gt; = 2中不再支持的ElasticSearch参数：

Remove boost which is now unsupported

在更改之前，django-haystack在_boost后端的映射中使用了ElasticSearch参数。对主分支进行了更改。你现在可以做的事情：

直接从github安装django-haystack的开发版本：

pip install -e git+https://github.com/toastdriven/django-haystack.git@master#egg=django-haystack

在升级到第二版之前将ElasticSearch降级到最新的稳定版本，我认为是1.7.3

另外，以下是相关讨论：

Django haystack LocationField created as string instead of geo_point in elasticsearch

使用elasticsearch在django-haystack中执行rebuild_index时的MapperParsingException
