如何在[Javascript + ElasticSearch]中带有条件的文档建立索引

Question

My program does his stuff and creates at the end a .csv with some data. I want to index a document with these data so I also call a function with something inside like this:

client.index({
index: 'blog',
  type: 'post',
  id: 1,
  body: {
    title: 'JavaScript Everywhere!',
    content: 'It all started when...',
    date: '2013-12-17'
  }
}, function (err, resp) {
  // ...
});

Now, what if for example I wanna have an "if" condition inside "body", for example store the title only if it is "Phyton"? . Similar question: what if I want to make an iteration having a "for"?

Thank you for helping.

Answer 1

You can't have if conditions inside body because you are creating a dictionary. You can have a simple ternary operation like

body {
  title: (t == "Python") ? "Python" : "Not Python"
}

You can't have a for loop either.

If you need to use complex condition statements to setup your data structure than you need to do that first and then pass it into your client.index function.
