Method search documentation
Retrieves the index of the array's first element corresponding to the given filter.
Example
```javascript
let ar = [
{name: "Raiders of the lost ark", director: "Steven Spielberg", year: 1981, id: 589},
{name: "Goonies", director: "Richard Donner", year: 1985, id: 689},
{name: "Star wars", director: "George Lucas", year: 1977, id: 256},
{name: "Jaws", director: "Steven Spielberg", year: 1975, id: 423}
];
bbn.fn.search(ar, "id", 256);
// 2
bbn.fn.search(ar, {director: "Steven Spielberg"});
// 0
bbn.fn.search(ar, {year: 1975, director: "Steven Spielberg"});
// 3
bbn.fn.search(ar, {director: "Steven Spielberg"}, 1);
// 3
// Complex filters
bbn.fn.search(ar, {
logic: "AND",
conditions: [
{
field: "director",
operator: "eq",
value: "Steven Spielberg"
}, {
logic: "OR",
conditions: [
{
field: "year",
operator: "eq",
value: 1974
}, {
field: "year",
operator: "eq",
value: 1975
}
]
}
]
});
// 3
Simple array
bbn.fn.search(['a', 'b', 'c'], null, 'b');
// 1
```
Retrieves the index of the array's first element corresponding to the given filter. - Returns -1 if the element is not found. If the second parameter is an object or function
for filtering as defined in bbn.fn.filter, the remaining parameters will be shifted to the
left, i.e. val becomes operator, and operator startFrom. And if operator is a number, its value will
be given to startFrom and operator will be undefined. The filter object can be complex with different
operators (as seen in bbn.fn.compare) and logics (AND/OR), and infinitely nested, of this form:
```javascript
{
logic: "AND",
conditions: [
{
field: "prop1",
operator: "eq",
value: "value1"
}, {
logic: "OR",
conditions: [
{
field: "prop2",
operator: "eq",
value: 1
}. {
field: "prop2",
operator: "eq",
value: 2
}
]
}
]
}
```
This way of managing the arguments is used in all the filtering functions.
