В поисковой строке я набрала фамилию клиента и нашла старый договор в архиве.

They are both past tense, feminine singular forms.

• набрать → набрала
• найти → нашла

In Russian past tense, the verb agrees with the subject in gender and number if the subject is singular.

So if the speaker is female, you say:

• я набрала
• я нашла

If the speaker were male, it would be:

• я набрал
• я нашёл

This is one of the first things English speakers notice, because English past tense does not change for gender.

Because фамилию is the direct object of набрала.

The speaker typed in the client’s surname, so фамилия has to go into the accusative case:

• nominative: фамилия
• accusative: фамилию

The second word, клиента, stays in the genitive case because it means of the client:

• фамилия клиента = the client’s surname
• набрала фамилию клиента = typed in the client’s surname

So the whole phrase means:

• фамилию = what was typed
• клиента = whose surname it was

Because договор is a masculine inanimate noun, and for masculine inanimate nouns, the accusative singular looks the same as the nominative singular.

So:

• nominative: старый договор
• accusative: старый договор

Since договор is the object of нашла, it is technically accusative, but the form does not change.

Compare that with an animate masculine noun, where accusative usually matches genitive:

• я вижу клиента not
• я вижу клиент

That is why клиента changes, but договор does not.

Because both phrases answer the question where?

• в поисковой строке = in the search bar
• в архиве = in the archive

After в meaning in, Russian often uses the prepositional case for location.

Examples:

• в доме = in the house
• в книге = in the book
• в архиве = in the archive

So:

• строка → в строке
• архив → в архиве

Also:

• поисковой is the prepositional feminine singular form of поисковая, agreeing with строке.

Поисковая строка means search bar or search field.

It is made from:

• поисковая = search-related
• строка = line / field

So literally it is something like search line, but in natural English it is usually search bar.

In the sentence, в поисковой строке means in the search bar.

Because it agrees with строке, which is:

• feminine
• singular
• prepositional

The base adjective is:

• поисковая строка = nominative

But after в for location, the noun changes:

• в строке

So the adjective must change too:

• в поисковой строке

This is standard adjective-noun agreement in Russian:

• same gender
• same number
• same case

Because the sentence describes completed actions with results:

• she typed in the surname
• she found the contract

The verbs are:

• набрать / набрала — perfective
• найти / нашла — perfective

Perfective verbs are very common when you talk about a single completed event in the past.

If you used imperfective verbs instead, the meaning would shift:

• набирала could suggest the process of typing
• находила is usually not right here for a one-time successful discovery

So perfective is the natural choice because the actions are seen as finished and successful.

Yes, набрать has several meanings depending on context. One very common meaning is to type in / enter text, numbers, or a name.

For example:

• набрать номер = dial a number
• набрать текст = type a text
• набрать фамилию = type in a surname

So in a computer or search context, набрать often means to enter by typing.

That is why набрала фамилию клиента sounds natural here.

Yes, very often.

Russian frequently drops subject pronouns when the verb form already makes the subject clear.

So this sentence could also be:

• В поисковой строке набрала фамилию клиента и нашла старый договор в архиве.

That still sounds natural, especially in conversation or in a narrative.

However, я may be kept for:

• emphasis
• clarity
• contrast
• a slightly more explicit style

Yes, Russian word order is flexible.

The given sentence is natural because it starts with the setting:

• В поисковой строке = in the search bar

Then it gives the subject and actions:

• я набрала фамилию клиента
• и нашла старый договор в архиве

This order sounds smooth and neutral enough in context.

But other orders are also possible, with different emphasis:

• Я в поисковой строке набрала фамилию клиента и нашла в архиве старый договор.
• Фамилию клиента я набрала в поисковой строке и нашла старый договор в архиве.

Russian word order often reflects focus and information flow, not just strict grammar rules.

Because нашла means found, while искала means was looking for / looked for.

These are different actions:

• искать = to search/look for
• найти = to find

In the sentence, the important result is that the speaker successfully located the contract, so нашла is the right verb.

Compare:

• Я искала старый договор. = I was looking for the old contract.
• Я нашла старый договор. = I found the old contract.

The second one emphasizes success.

Клиента is in the genitive singular.

It depends on фамилия and means of the client:

• фамилия клиента = the client’s surname

This is a very common Russian pattern where English would often use ’s or of:

• номер телефона = phone number
• имя клиента = client’s name
• фамилия клиента = client’s surname

So клиента is not the main object of the sentence. It is part of a noun phrase describing whose surname was entered.

Yes. Договор is a very common and natural word for contract or agreement, especially in business, legal, or administrative contexts.

So:

• старый договор = an old contract

In this sentence, it fits very well, because searching archives for a client’s old contract is exactly the kind of context where договор is used.

Placing в архиве at the end is natural because it gives the final piece of information: where the contract was found.

Russian often puts important or newly introduced information later in the sentence. Here the flow is roughly:

1. where she typed
2. what she typed
3. what she found
4. where she found it

So the ending в архиве works well as the final detail.

You could also say:

• ...и в архиве нашла старый договор

but that slightly shifts the emphasis. The original version is very natural.
