我正在使用弹性搜索.我需要弹性搜索的结果作为csv文件.任何卷曲网址或任何插件来实现这一目标？提前致谢.
任何人都可以向我解释为什么9999999999999999被转换为10000000000000000？
alert(9999999999999999); //10000000000000000
我使用以下代码在Elastic Search,Default JAVA API中创建索引:
Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "myClusterName").put("client.transport.sniff", true).build();
Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9200));
CreateIndexRequestBuilder createIndexRequestBuilder = client.admin().indices().prepareCreate("test1");
CreateIndexResponse response = createIndexRequestBuilder.execute().actionGet();
System.out.println(response.isAcknowledged());
REST服务:
HttpURLConnection con = null;
try
{
String url = "http://localhost:9200/test2";
URL resturl = new URL(url);
con = (HttpURLConnection) resturl.openConnection();
con.setDoOutput(true);
con.setRequestMethod("PUT");
BufferedReader in = null;
try
{
if (con.getInputStream() != null)
{
in = new BufferedReader(new InputStreamReader(con.getInputStream()));
}
}
catch (IOException e)
{
if (con.getErrorStream() != null)
{
in = new BufferedReader(new InputStreamReader(con.getErrorStream())); …我在输入时使用以下代码转换为大写.
$(".input_capital").live('keypress', function(e)
{
var defaultStr = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
var checkstr = $(this).val();
var str1 = '';
for (i = 0; i < checkstr.length; i++)
{
var ch = checkstr.charCodeAt(i);
if (ch>=97 && ch<=122){
str1 += defaultStr.charAt(ch-97);
}else{
str1 += checkstr.charAt(i);
}
}
$(this).focus();
$(this).val(str1);
});
以下代码
$(".input_capital").live('keypress', function(e)
{
$(this).val($(this).val().toUpperCase());
});
以上所有代码都运行正常.但对于能够查看较低情况一段时间的用户.之后只有它转换为大写.
我text-transform: uppercase在css中试过' '.但它不适用于Android Os的三星标签.请任何人帮助我通过脚本实现这一目标.
我是Elastic Search的新手.有没有办法获得搜索关键字的所有搜索结果？弹性搜索限制为10,否则我们可以设置大小但我们需要获得大小？
弹性搜索 Java Api 中的批量更新会引发以下异常。

BulkRequestBuilder bulkRequestBuilder = client.prepareBulk(); …嗨,我正在使用弹性搜索elasticsearch-0.90.2版本.我正在尝试使用jsonBuilder使用自定义分析器映射分析器,同时创建索引,它会抛出异常,就像找不到分析器一样.
设置 :-
XContentBuilder settings = XContentFactory.jsonBuilder()
.startObject()
.startObject("settings")
.startObject("analysis")
.startObject("analyzer")
.startObject("search_analyzer")
.field("tokenizer", "ngram_specification")
.field("type", "custom")
.field("filter", new String[]{ "ngram_specification"})
.endObject()
.endObject()
.startObject("ngram_specification")
.field("type", "nGram")
.field("min_gram", "2")
.field("max_gram", "5")
.endObject()
.endObject()
.endObject()
.endObject();
制图: -
XContentBuilder mapping = XContentFactory.jsonBuilder()
.startObject()
.startObject("sample")
.startObject("properties")
.startObject("email").field("type", "string").field("index", "analyzed").field("analyzer", "search_analyzer")
.endObject()
.endObject()
.endObject()
.endObject();
像这样创建索引: -
CreateIndexRequest indexRequest = new CreateIndexRequest(indexName);
indexRequest.settings(settings);
indexRequest.mapping("sample", mapping);
CreateIndexResponse response = client.admin().indices().create(indexRequest).actionGet();
例外:
